摘　　要：文章针对一起铁厂接入电网造成电能质量劣化这一问题,首先根据电网参数和厂家资料,利用公式推导计算电网电压波动和闪变值的超限情况;并在电力电气分析、电能管理的综合分析软件(ETAP)中搭建仿真模型进行计算,得出电压谐波含有率及谐波电流注入超限次数。根据对比计算结果,给出了电能质量治理建议,并通过后续实时监测,验证了文章中所提出的治理建议的有效性和合理性。In view of the power quality problems caused by the connection of iron plants to the power grid,according to the power grid parameters and manufacturer data,the overrun of the voltage fluctuation and flicker value of the two sections of the power grid is first deduced by formula.Then,the simulation model is built in ETAP software,and the voltage harmonic content rate and harmonic current injection overrun times are calculated by simulation.Combined with the formula derivation and simulation results,the power quality control measures are given.The effectiveness and rationality of the proposed treatment measures are verified by the follow-up real-time monitoring.
