大功率设备在电网波动下的研究对策

针对电网短暂波动或短时断电导致交流接触器脱扣的问题。设计一种在检测交流侧电压不正常情况下控制继电器切换到储能器件,避免交流接触器在电网波动情况的不正常工作的控制器;从而达到当电网波动出现时交流接触器维持吸合状态,实现在控制延迟的时间后断开。结果表明采用防电网波动控制器,能够有效解决交流接触器脱扣的问题,从而有效的避免电网波动事故的发生,使整个系统能够连续安全、可靠的运行。

Countermeasures of electrical power in the power network fluctuation

Temporary or short-term fluctuations in the power grid caused by AC ontactor tripping problems.In the detection of the AC side voltage irregularities,controled relay switching to energy storage devices by selecting the appropriate storage device aim at pulling maintain status for AC contactor,which is reached after turn-off in the case of the control delay time. The results showed that Using of anti-power fluctuations controller can effectively solve the problem of AC contactor trip so as to effectively prevent the occurrence of accidents power fluctuations, so that the whole system is capable of continuous safe and reliable operation.
