Coordinated control of battery energy storage and diesel generator in independent AC microgrid:

In the independent AC microgrid system, the coordination control between the diesel generator and the battery energy storage is the key to ensure the stable operation of the system. Based on the fast response characteristic of battery energy storage, a coordinated control method of diesel generator and energy storage battery was proposed. When the diesel generator is used as the main power supply, the auxiliary power control signal is introduced into the traditional droop control of the energy storage system to prevent the system collapse caused by the diesel engine overcurrent for a long time and improve the system stability. Aiming at the short-time power outage problem when the main power supply in the microgrid changes from the energy storage system to the diesel generator or from the diesel generator to the energy storage system, a seamless switching control strategy of the two main power supplies of the diesel generator and the energy storage battery is proposed

The principle of:

In short, a diesel generator drives a generator.

In the cylinder, the clean air filtered by the air filter is fully mixed with the high-pressure atomized diesel oil sprayed by the nozzle. Under the upward extrusion of the piston, the volume shrinks and the temperature rises rapidly to reach the ignition point of the diesel oil. Diesel is ignited, the mixture of gas intense combustion, rapid volume expansion, push the piston down, known as' work '. Each cylinder works in a certain sequence, and the thrust force acting on the piston becomes the force pushing the crankshaft through the connecting rod, thus driving the crankshaft to rotate. The brushless synchronous alternator and diesel generator crankshaft are installed coaxial, can use the rotation of the diesel generator to drive the rotor of the generator, using the principle of 'electromagnetic induction', the generator will output induced electromotive force, through the closed load loop can produce current.

Only the most basic working principle of a generator set is described here. A range of diesel generators and generator controls, protection devices and loops are required for a usable, stable power output.

Our factory can produce portable diesel generator set. This kind of products can be used at home, office, fieldwork and many other work. We can supply this kind of products with power including 2KW, 3KW and 5KW Structural style: Open type, semi-open type, silent type. Single phase or three phase. Have CE(CONFORMITE EUROPEENNE) certifiCAT-parts-partse. Have steady quality and competitive price.

This air-cooled diesel generators are widely used when electrical power is scarce, Our welders provide a portable mobile solution in supplying power for field operations during project construction.

Since establishment in 1985, Guangdong ALI Testing Equipment Co., Ltd, a wholly-owned subsidiary of GSKA Group has been providing a wide and complete range of products and services to the society. GSKA has now 16 offices, warehouses and service centres in China, with head office loCAT-partsed in Hong Kong. There are more than 100 employees in GSKA Group, and we are expanding into many industries with rapid expanding pace of China.

There are mainly 4 departments in GSKA Group, namely:

1) Construction and Mining equipment

GSKA has been cooperating with many international famous brands in China, such as Ingersoll-rand, Atlas Copco and Liebherr. Our products include concrete batching plants, concrete mixers, hydraulic crawler drills, pneumatic crawler drills, water well drills, air compressors, road compactors, breakers and various other equipment. We are major in several industries, such as hydro-electric power plants, cement quarries, coal mines and railway systems.

In order to provide a quick response to our customers, we have stocked over US$1.5 Million spare parts of Ingersoll-rand and Atlas Copco in our Chinese warehouse. Recently, we have exported small air compressors, pneumatic crawler drills, water well drills and drilling accessories and spare parts to overseas market.

2) Power Group

GSKA has been supplying CAT-parts and Broadcrown gensets for more than 15 years. Our major customers include Telecoms, Banks, Airports, Factories and many other sectors in the society. We are also doing assembly of gensets in China, under our brand name of "GSKA " with ratings from 1KVA to 2000KVA. The quality of "GSKA " genset has won a very good reputation from customers in China and overseas market.

We are also the specialists for genuine spare parts, such as CAT-parts, Perkins, FG Wilson, Cummins, , Volvo, etc.

Besides gensets, we also provide total solution on the power problems, such as Powerware - UPS, DC system and battery ,lightning equipment and many other electronic products.

3) Security and IT Group

GSKA acquired famous USA brand name Locktronix in 2004 and started manufacture electric locks in China. Since then, we have been exported products to the Middle East, South Asia and Africa. Our market is expanding each year and we are looking for more distributors in different countries to be our business partners. Besides electric locks and accessories, we have also developed our own access control system by our software team. The system includes smart card solution and also biometric access control, such as hand-key, fingerprint and facial recognition. Our EC-PAYROLL system has been widely used in many factories both in Hong Kong and mainland China.

After all, GSKA has an objective of "Always Provide the Best" and we shall consistently provide high quality products and reliable services to our worldwide customers. We are looking forward to making good business with our partners
