Speed regulation on generators: power without ups and downs

/in , /by

Technical Article. Pic of a man manipulating speed of a generator set.

What we demand of a generator is a stable power delivery. And a constant engine speed is crucial in achieving this.

A speed generator set must maintain a consistent engine speed, as this directly affects power frequency and overall performance.

The famous Swiss architect Le Corbusier said that machines are “a fantastic perfection tool”. However, experience tells us that even the most sophisticated machinery is not perfect. Although the mechanical systems are designed to be balanced and deliver based on optimal parameters, one must take into account that there are always some factors which can alter their efficiency.

The speed of an engine, for example, may be affected by a drop in voltage or by power surges. And, in the case of generators, such variations are of critical importance, given that the engine speed directly determines its operating frequency.

Logically, this can entail a problem, because the thing that interests us about a generator is that it be capable of maintaining the most stable power possible around a certain value.

The good news? Everything is foreseen and technology provides us with the solutions for the engines never to lose direction.

Generator speed control systems: ensuring reliable power output

At present, the engines powering electrical generators contain a speed regulator for speed control.

The function of this regulator is to detect any imbalance in the engine speed and to cause it to revert quickly to its optimal working regime.

Thanks to this device, our generator’s engine will always keep a constant rhythm. In this way, the generator will be capable of always complying with the requirements of the load, giving us the power that we need to obtain.

Moreover, the speed regulator acts as a security device, because it protects the engine from excessive speeds which can cause the engine to break down.

What controls engine speed in engines that power generators?

Engine speed in generators is controlled by a speed governor, also known as a generator speed controller. This device monitors the engine’s RPM and adjusts the fuel supply to maintain a stable speed under varying load conditions. In modern generator sets, this can be mechanical, electronic, or a combination of both systems.

Genesal Energy: reliable engines

At GENESAL ENERGY, we offer you diesel generators equipped with three different types of governed engines:

  • Engines with mechanical controls
  • Engines with mechanical controls and inbuilt electronic controls
  • Electronic engines

All of these are designed to recuperate the working frequency, both after a load impact and after a sudden drop thereof.

The response to the drop in frequency will depend on:

  1. The inertia of the engine itself.
  2. The inertia of the alternator.
  3. The characteristics allowed by the installed AVR (Automatic Voltage Regulator).

At the same time, in the engines with mechanical speed regulation, we apply a parameter called “speed drop” or “droop”. This parameter represents the percentage of over-speeding that the engine is experiencing when it is operating without a load, compared to the nominal speed (at full load). Once we have calculated this, we can configure the engine so that it quickly stabilizes when a load is applied to it.

 

 

 

All regulators need a certain period of time in order to act. At GENESAL ENERGY, we carry out all the necessary adjustments and tests to ensure that the regulators control the engine speed and the generator frequency correctly. In this way, we give a reliable response to our clients’ requirements.

How do variables affect Generator Sizing?

/in , /by

Analyzing the effect of voltage and frequency drops is indispensable for deciding which engines and alternators are more adequate for a generator.

Voltages are not a static phenomenon. They fluctuate resulting in peaks and drops during certain phases of the equipment’s functioning.

In fact, when we speak about circuits we distinguish between two types of situations:

  • The steady condition: It is the stationary situation of normal functioning in which the voltage ows in a balanced state according to the conditions determined by the network.
  • The transitional state: it occurs in certain periods of time in which the voltages and electrical intensities vary, before the circuit comes to its steady state and becomes stabilized.

The voltage variations occurring during these transitional periods are known as variables.

When do variables occur?

Logically, the normal situation in which variables occur is when we cause a circuit to pass from one condition to another, i.e. at the moment of connecting or disconnecting the equipment.

In fact, when we switch on and off a generator, short voltage peaks are triggered. Although they tend to end by themselves, we must not take them easily. Why is that? Because if the alternator and the engine happen not to be capable of coping with them, major functioning problems may ensue in the generator.

A matter of analysis

For this reason, in the process of designing and sizing a generator, it is indispensable to carry out a strict variable analysis.

Do you want to know the keys to be able to do this analysis?

We supplied an emergency genset with an aseismatic system for the Carrasco electrical substation (Bolivia)

/in , /by

Guaranteeing power supply in extreme situations is one of Genesal Energy’s specialties. Genesal’s emergency genset designs are always carried out according to the client’s needs.

The Carrasco electrical substation, in Cochabamba (Bolivia), is one of our latest projects in the country and a great example of seismic engineering.

For the Carrasco substation, the client needed a genset with very specific needs, as the installation is located in a very sensitive area, which is quite vulnerable to earthquakes. With the objective of facing this possibility and avoiding a catastrophe, our engineering team carried out a thorough study after listening to the client and analyzing the site in which the genset would be installed.

Upon receiving all required information, Genesal Energy manufactured a very precise genset, with all the necessary special systems to protect the Carrasco electrical substation. The result is a unit which, amongst other features, has anti-seismic mounts, and spring mounts between the base frame and the floor. A vent for the channelling of the cooling air to the outside, and a 1.700 litre fuel tank -which in this case was reinforced to comply with anti-seismic regulations- are just a few examples of the features of this genset, whose goal is to avoid failures in the mains supply which provides power to millions of citizens, at all times.

Features

  • Anti-seismic mounts.
  • Spring mounts between the baseframe and the floor.
  • Vent for the channelling of the output cooling air to the outside.
  • Reinforced 1700 litre baseframe fuel to comply with anti-seismic regulations (without certificate).
  • IVECO NEF67 TE2A engine at 24V.
  • Mecc Alte ECO 38-2S alternator at a voltage of 380/220.
  • 3400×1350 mm soundproof canopy.
  • RAL 9002 genset colour.
  • IEC61850 communication.

Genesal emergency power for Topolobampo III, the combined-cycle power plant which will provide electricity to 2,5 million Mexican citizens

/in , /by

The Topolobampo III combined-cycle power plant, located in the Mexican state of Sinaloa features a special soundproof genset, with a control cabinet integrated inside the container, designed and manufactured in our headquarters in Bergondo (A Coruña).

With an investment of more that 400 million dollars, Topolobampo III is the latest great power generation project in Mexico, a country in which our company has a great presence, and where it has had its own branch office for years. The 767 megawatts (MW) combined-cycle power plant, carried out by the Mexican Federal Electricity Commission (CFE), is located in the municipality of Ahome, and will provide electricity to more than 2,5 million citizens. The plant will begin operating in 2020.

Due to our strong presence in Mexico and our knowledge of its terrain, the genset designed for Topolobampo III was adapted to the special conditions of this type of combined-cycle power plant, which contains special loads which must be permanently powered for the correct operation of the facilities. For instance, the lubrication pumps or cooling units must always be operational so that, in the event of an emergency such as a power outage, the whole system can be shut down securely. This is precisely the function of the genset we manufactured for the plant.

Made-to-measure

We designed a bespoke genset, soundproofed in a container which was also tailor-made with specific elements (air conditioning, motorized louvers, fans, etc.), manufactured to adapt to the client’s concretes needs.

Furthermore, the automation of the genset allows the necessary integration of the external ATS and the different switches managed by the genset, so that the start-up and stop sequence expected by the client is followed at all times.

Due to space limits, a fuel capacity of 4000L was integrated inside the container through double-walled fuel tanks to guarantee the continuous operation of the genset for over 10 hours at 100% load. The unit is also designed to start up without the need of any type of external voltage, without needing secure voltage for the control circuit.

Main Features

  • Exterior build: 40’’ HC container suitable for marine transport 
  • Control cabinet integrated inside the container 
  • Engine cooling liquid recirculation and heating system, in order to provide the right temperature for genset start-up. 
  • Air conditioning system in the genset’s control room. 
  • Motorized louvers in the air inlet and outlet. 
  • Redundant fans to control the temperature in the engine room.
  • C51 container surface treatment according to the ISO 12944 standard.
  • Alternator anti-condensation heating. 
  • Temperature sensors in the alternator’s windings and bearings. 
  • 4000L fuel tank integrated in the container with leakage detection. 
  • Management of the genset’s control system and associated systems of the client’s facilities through a controller and touch-screen. 

Genesal Energy consolidates its position in the health sector with high precision gensets for large hospitals

/in , /by

The Galician company increases its national presence with emergency gensets for the new hospitals in Cuenca and Guadalajara.

The design of highly reliable gensets, which allow to continue tending to patients even in the event of a mains failure, is of maximum priority when it comes to supplying emergency gensets to any hospital, and this is a field in which Genesal Energy has reinforced its presence in recent years both nationally and internationally. The very nature of these facilities calls for customised units, and behind each one is a complex engineering development.

The Galician company has consolidated its presence in Spain through new projects carried out hand in hand with Imoel, a company which has specialised in the electricity sector for over 35 years, and which has trusted in Genesal since 2009 for delicate projects such as the expansion of the Guadalajara hospital, where it will supply two 1,500/1,650 kVA gensets, and Cuenca’s new hospital, which while still in its construction phase, will be a magnificent hospital complex with 12 buildings for which Genesal Energy was in charge of designing, manufacturing and supplying three 1,400/1,540 kVA emergency gensets.

Maximum reliability

Both hospitals will include soundproof gensets which were completely tailor-made for the client, and therefore, adapted to the requirements of the buildings in which they will be installed, completely prepared to face any potential incident.

In this sense, all five gensets have a common denominator: to guarantee power supply at all times, as in hospital complexes, any failure in the mains supply can cause serious problems, both for the medical equipment -which nowadays is highly technological, especially in emergency and operating rooms- and the patients alike.

A reference company, both nationally and internationally

Genesal Energy’s participation in these projects is part of the company’s major focus on the health sector, where it’s increased its presence in recent years both nationally and internationally, through the supply of emergency power to hospitals such as the Quito-Sur Hospital, the largest and most modern in Ecuador, a country in which the Galician company is one of th reference brands.
