摘要

为了将电压控制在可接受范围内，提出了基于IEC 61850标准的光伏电站无功补偿方案。在光伏电站太阳能逆变器中采用伏特/VAR控制，既可以提高电能质量，又可以减少由于过电压造成的太阳能逆变器断网。因此，光伏电站的所有者将有更多的机会将太阳能电力卖回电网。对于Volt/VAR控制，采用PQ模式的太阳能逆变器控制系统的有功功率和无功功率。变电站的电力数据根据IEC 61850标准发送到PLC, IEC 61850是变电站系统的通信标准。本文的仿真结果验证了Volt/VAR可以改善光伏电站的电能质量。

Reactive power compensation for solving voltage problems in PV farm based upon IEC — 61850

Reactive power compensation for solving voltage problem in PV farm based upon IEC 61850 is presented in this paper in order to control voltage within acceptable range. The Volt/VAR control is used in solar inverter of PV farm to improve power quality and also reduce the disconnection of solar inverter caused by overvoltage. So, the owner of PV farm will get more opportunity to sell solar electricity back to the grid. For Volt/VAR control, solar inverter with PQ mode is used to control the active and reactive power of the system. Electricity data from substation are sent to PLC based upon IEC 61850, which is the standard communication of electrical substation system. In this paper, simulation result verifies that Volt/VAR can be improve a power quality in a PV farm.
