doi:10.11930.2015.3.103

摘要/Abstract

摘要： 从静态电压安全角度出发，对风电场静态电压偏移进行分析，提出了风电场静态安全运行范围的概念；基于电压约束条件，通过对风电场外送功率的线性变换，建立了风电场的静态安全运行范围，定义了运行点至边界的安全运行距离，并进行风电场稳态运行工况下的电压预警研究；通过无功优化的方法改善风电场的静态电压安全，给出其计算方法。在DIgSILENT/PowerFactory仿真软件上进行了仿真验证，仿真结果验证了所提静态安全运行范围对风电场的适用性。基于此可实现风电场的静态电压预警和无功优化分析，为风电场的安全稳定运行提供方法支持。

Abstract: Static voltage deviation of wind farm is analysed based on static voltage security. Static safe operation range of wind farmer is proposed in this paper by using linear transformation of power output based on voltage constraints. The safe distance between wind farm operating point and security boundary is defined and voltage forewarning is investigated under steady-state operating conditions. A reactive power optimization method is proposed to improve wind farm static voltage security. The simulation results with DIgSILENT/ Power Factory software show that the proposed static safe operation range has good applicability for wind farms. The proposed method provides methodological support for the safe and stable operation of wind farms, and can be used to realize static voltage forewarning and reactive power optimization.

Key words: wind farm, voltage deviation, static safe operation range, boundary, safe distance, voltage forewarning, reactive power optimization, linear transformation
