SmartGen parallel control modules include HGM9510, HGM9520 and HGM9560. HGM9510 is multiple gensets parallel control module and is also called single unit constant power parallel with grid control module. HGM9520 control module is single unit parallel with grid control module and has multiple parallel with grid modes. HMG9560 control module is multiple units parallel with grid control module. Multiple gensets parallel before paralleling with grid and there are multiple parallel with grid modes.
Multiple Parallel with Grid Modes:
Electric Generation Constant Power Mode: After paralleling with mains, the output power of genset is constant. Redundant power outputs to mains if output power is greater than load demand; insufficient power is provided by mains if output power is less than load demand. As shown in Figure 1:
Mains Peak Clipping Mode: Setting the power value of mains on load and the power that beyond setting value is provided by gensets. As shown in Figure 2:
Mains Reception Mode: Setting mains constant received power value, the genset output power is the sum of load demand and mains constant receiving power. (Output to mains when the value of curve is negative) As shown in Figure 3:
Load Reception Mode: power supply switchover between mains and gens based on the validity of input port of remote start on load. (①: Remote start on load input is active ②: Remote start on load input is reactive) As shown in Figure 4:
AMF mode: The genset start and supply power automatically when mains is abnormal; the genset shutdown automatically and mains supply power when mains is normal. (①: Mains abnormal ②: Mains normal) As shown in Figure 5:
Island Reception Mode: Power supply switchover between mains and gens based on the validity of island input port of remote start. (①: Remote start island input is valid ②: Remote start island input is invalid) As shown in Figure 6:
