发电机组并联运行有功、无功综合调控技术

Technology of General Adjusting and Controlling Active Power and Reactive Power of Generator Set Operating in Parallel

介绍了发电机组的转速、电压控制原理以及有功、无功综合调控技术的控制原理;并通过实例介绍了采用该控制技术的船舶电站监控系统。实践表明,融合有功、无功综合调控技术的电站监控系统在投入运行后,实现了任意组态下,并联机组有功、无功功率稳定的自动调整,使得多个电站机组长期并联运行更加可靠。

This article introduces the speed and voltage control principle and the control principle of general adjusting and controlling active power and reactive power technology in generator sets, and the marine power station monitoring system adopting the controlling technology by examples. The system has the functions of auto-controlling, monitoring-alarm-display, safe protection and inter locking. The practice shows that the power station monitoring system with active and reactive power controlling technology is able to automatically adjust the generator sets in parallel to be balanced in active and reactive power supply steadily in any combination after the system is in operation. Thus, the sets in parallel can work more safely for a long time.
