摘要: 针对光伏接入后造成的高低电压越限交织问题,分析配电网线路台区电压越限机理,研究光伏逆变器双闭环控制和有功无功出力特性。在此基础上,提出基于光伏逆变器功率控制的配电变压器台区调压策略,实现不同工况下末端配电变压器台区电压均在合理区间。通过仿真验证了控制策略的有效性。

Abstract: Due to the regularity of photovoltaic output, there is a phenomenon of high and low voltage cross‍ing and interweaving in the distribution substation area after photovoltaic integration, which seriously affects the safe and reliable operation of the distribution network. To address the issue of high and low voltage crossing caused by photovoltaic integration, the paper analyzes the mechanism of voltage crossing in the distribution network substation area, and studies the dual closed-loop control and active and reactive power output characteristics of photovoltaic inverters. On this basis, a voltage regulation strategy for the distribution transformer substation area based on photovoltaic inverter power control is proposed to achieve a reasonable range of terminal distribution transformer substation area voltage under different operating conditions. The effectiveness of the control strategy is verified through simulation.

Key words: distributed photostatic, photovoltaic inverters, distribution substations, high and low voltage overruns, voltage regulation strategies
