Abstract

With the increasing proportion of new energy in power systems, issues regarding system voltage, inertia, and primary frequency regulation have become increasingly severe. In response to control and grid safety issues, a high proportion of new energy power system frequency and voltage support and regulation technology based on a doubly fed induction generator (DFIG) is proposed. The voltage-magnetic link equation of DFIG is theoretically derived, and the control principles of active and reactive power of DFIG are proposed. The support and regulation characteristics of improving the voltage of new energy substations are studied. Verification is conducted through large-scale grid simulation and on-site measurements.
基于双馈异步发电机的高比例新能源电力系统频率和电压支持与调节技术
随着新能源在电力系统中所占比例的不断增加,系统电压、惯性和一次频率调节等问题变得日益严峻。针对控制和电网安全问题,提出了一种基于双馈异步发电机(DFIG)的高比例新能源电力系统频率和电压支持与调节技术。从理论上推导了双馈异步发电机的电压-磁场联系方程,提出了双馈异步发电机有功和无功功率的控制原理。研究了改善新能源变电站电压的支持和调节特性。通过大规模电网仿真和现场测量进行了验证。
