摘要
在分析直流闭锁对送端系统电压特性影响的基础上,提出一种风火电和电容器协调的紧急控制和优化切机策略。该策略在保证系统稳定的基础上,通过优化整流站电容器的切除量和风火电切机量的分配,使恢复系统稳定所需的风火电总切机量最小。最后以西北某风火打捆直流外送系统为算例,验证所提协调控制策略的有效性与实用性。
Based on the analysis of the influence of HVDC block on the voltage characteristics of the sending end system,a thermal/wind power units and capacitors coordinated urgent control and optimal tripping strategy was proposed.This strategy optimizes the capacitor amount of the rectifier station and the distribution amount of thermal power and wind power aiming at the minimum total amount of tripped units.At last,validity and practicability of the proposed strategy was verified based on an actual wind-thermal-bundled HVDC transmission system in Northwest China.
