摘要:

为了对分布式光伏电站接入点电压进行有效控制，给出了一种含分布式光伏电站接入的配电网三级电压控制系统设计方法。通过对分布式光伏电站特点的分析，从系统结构、控制模式、数据通信、控制策略等方面对电压控制系统的设计方法进行了详述。工程算例结果表明，基于智能分区控制技术的光伏电站电压控制系统设计方法是有效和实用的。该系统对并网点电压、站内电压、功率因数进行多目标优化，可实现分布式光伏电站电压的综合协调智能控制，大大提升分布式光伏电站的并网友好性。

Abstract:

A schema of three level automatic voltage control system in distribution network with the connection of many distributed photovoltaic power plants is introduced. Through the analysis on the characteristics of distributed photovoltaic power station, the system structure, control mode, data communication, the design method of voltage control strategy is introduced in detail. The engineering examples show that, the design method of PV power station voltage control system of intelligent control technology based on partition is effective and practical. It can optimize the PCC voltage, power factor, and can make distributed photovoltaic power plant more friendly and efficient.

Key words: distributed PV power station distribution network PCC AVC intelligent zoning control
