Two or more sets are used to provide power to the load, sharing power equally as a percentage of the sets full load rating. Sets are automatically started and stopped depending upon load levels allowing economic use of the available generators.

If there is mains power, two or more sets are used to provide backup to the mains supply. When the mains supply fails, the sets are started, synchronised and paralleled together. The generators bus is then closed to feed the load, the sets sharing power equally as a percentage of their full load rating. Sets are automatically started and stopped depending upon load levels allowing economic use of the available generators. When the mains supply returns, there will be a break in supply to the load while the transfer takes place.

SYNCHRONIZED OPERATING SYSTEM

In case user provides information about the desired system when system is in installation stage, synchronized system can be designed accordingly. There are 3 different types of synchronized operating systems.

In case network power excesses the desired values or if it completely breaks down, synchronized system may be operated in following modes:

1. Manual Operating: User will have the control. Generators are operated by pressing start button. After it gets ready, generator is shutdown by cutter shutdown buttons and it gets synchronized in synchronous bus. Then, G1 main generator cutter steps in and the system is provided power. As regards to feedback, after ensuring the input of network power, main generator cutter is disabled and main network cutter steps in. Generators are shutdown upon idling for a while.

2. Automatic Power Back-up Operation: Control is by modules. If there is no network power, generators operate simultaneously. The first ready synchronous is connected to bus, and the other ones begin to feed the load as main synchronous upon shutdown of main generator. According to the status of load, master module disables un-required generators or in case of subsequent increase in load, it recalls and ensures synchronization. By the input of network power, main generator cutter is automatically disabled and the load is transferred to network.

3. Automatic Failure Back-up Operation: Control is by modules. If there is no network power, only 1 of the generators operates and main generator cutter is shutdown and the load begins to be fed. In case of any failure in any operating generators, other generator immediately steps in and receives the load by synchronizing and ensures the disablement of failed generator. By the input of network power, it transfers the load to network. Then, it disables after cooling begins to operate.

Generator control module is the device that enables the generator it controls to operate and then performs checking from generated voltage to radiator water level amount and provides power with the system by controlling cutter if everything is in normal values. Furthermore, it is used in order to stabilize and connect it to synchronized system, frequency and voltage values of generator by communicating with other generator control modules connected to synchronous system.

CONTROL MODULES CONFIGURATION WITH SOFTWARE

The control modules configuration software allows the modules to be connected to a PC.

Once connected the various operating parameters within the module can be viewed or edited as required by the engineer. This software allows easy controlled access to these values and also has diagnostic monitoring facilities.
