    摘 要:介绍了某试验变电站拟进行的各种试验方式,对试验站在公共连接点产生的电压波动和闪变、有功冲击进行了仿真计算,得出该试验站需满足国标关于电能质量限值要求的试验容量为196 MVA,大于此容量则需要采用冲击发电机进行试验。建议试验单位应与电网相关部门相互合作,采取相应措施,使试验站冲击负荷对电网的影响满足国标限值要求。

    Abstract: Introduction was made to various kinds of test methods planned for certain experiment station. This paper carried out simulation calculation for the voltage fluctuation, flicker and active power impact produced in the point of common coupling of experiment station, and obtained that the test capacity was 196 MVA, which was satisfied for national standard about power quality limiting value. If the capacity was larger than the value, the impulse generator would be used to carry out the experiment. It is suggested that the testing agency should cooperate with the relevant departments of power grid and adopt the corresponding measures to make the impact load of experiment station have little influence on power grid which meets the national limiting value.
    Key words: experiment station; voltage fluctuation; flickering; active power impact; power quality
