Gas Gensets Parallel Sample
By Zhou Zhitian, Service engineer of SmartGen
The customer needs two gas gensets parallel first, then parallel with grid in a Shanxi station. Normal mains supply certain load and generator set standby, in the peak time, consider the electricity cost, a generating set automatic starts close, another unit for standby, power generation and mains parallel with grid, power for the rest extra load. If the rest load is more than rated power of single unit, and a backup unit automatic close gensets parallel, then parallel with grid, load sharing for two units to achieve the peak clipping mode.
When the load is reduced to a single unit for load, the standby unit with automatic load transfers to the main unit, the standby unit open.When the load is reduced to the mains to load, the main unit with automatic load is transferred to the mains, then open, the mains for load.
The efficient use of energy is a major bright spot in this project. The cooling water tank of two units, using a water tank of 12 cubic, the hot water of circular cylinder, the hot water from the tank to heat gas pump through the unit operation.
The project uses two HGM9510 parallel units cabinet and a HGM9560 parallel with grid cabinet, automatic load peak clipping mode can be realized after simple setting. It can reduce customer's electricity cost.
