摘要:
县级孤网运行在高负荷时，经常发生无功缺额情况，造成电网电压质量不满足用户要求；本文主要介绍了利用PSD-BPA潮流计算软件进行县级电网潮流计算的方法及要点，并介绍了配电网无功补偿的原则和方法。最后以海南省乐东县电网为例，介绍了考虑小水电群的乐东电网无功优化结果。对乐东配电网进入孤网模式下，无功优化中的补偿设备安装位置和补偿容量进行了研究，通过无功优化前后的对比，得出变电站集中补偿能较好的解决乐东电网出现的电压质量问题。
When the isolated network is operating at high load, the reactive power shortage is often occurred, and the voltage quality of the grid is not satisfied with the user’s requirement. This paper mainly introduces the using PSD-BPA power flow calculation software of county-level power flow calculation method and points, and introduces the distribution network reactive power compensation principle and method. Finally, taking Hainan province Ledong County power grid as an example, it introduces the reactive power optimization results of Ledong small hydro power group. Of Ledong distribution network in islanded mode, no compensation device for reactive power optimization in installation position and compensation capacity was studied. Through the contrast before and after reactive power optimization, it is concluded that the substation centralized compensation can solve the Ledong grid voltage quality problems.
