Parallel Control Panel 1000A For Two Or More Generator Sets Synchronous Running

SHX full auto synchronous control system has auto synchronization and auto parallel operation for each genset:

• When one genset is running on load, if the load is close to 80% of rated load (adjustable), send signal of genset adding automatically, standby genset starts up automatically, and parallel operation automatically after auto synchronization, distribute active load automatically and averagely, distribution difference is less than ±10%.
• When one genset is running on load, if the genset has fault, the system will disconnect the faulty genset automatically and send signal of genset adding automatically, standby genset starts up automatically, switch on and supply power.
• When two gensets are running, the total load less than 20% (adjustable), the system will send signal of genset decrease, standby genset unload and disconnect, shut down automatically after maintained running.

Operation:

1. Starting up one of gensets manually, switching on after running normally.

2. After that, starting up the second genset, put the switch to on position, at the moment the system detects automatically and control parameters of two gensets, including voltage, phase sequence, frequency and phase position, when it achieves condition of parallel operation, the system will bring in the second genset to parallel running automatically.

3. After parallel connection of two gensets, no matter how does the load change during running, the system will distribute active load and reactive load automatically according to the size of gensets, the distribution difference is less than +10%.

4. When gensets are in synchronous running, it can quit one genset through the order of “unload”, transit the load of this genset smoothly to another genset, and then switch off, shut down after time delay, which can avoid damage of genset due to load and unload suddenly.
