高铁牵引负荷对电力系统暂态能量分布的影响
Study on Influence of HSRW Traction Load on Transient Energy Distribution of Power System
摘要
Abstract
ABSTRACT:Study of high-speed railway (HSRW) influence on transient energy distribution of power system can provide a basis for recognitionand control of power system vulnerable sections passed by HSRW. By analyzing moving impact characteristic of HSRW traction load and the feature that HSRW can change power-flow distribution of power network in short time, influence of HSRW on transient energy distribution and stability of power system disturbed is studied. If traction load can make transmission power in cut-set branches increase, accumulation degree of transient energy in cut-set branches will aggravate. But energy accumulation degrees aredifferent according to power system strength. Energy accumulation degree is bigger for more vulnerable power grid passed by HSRW. When the power system is subjected to disturbance, if traction load just moves to vulnerable section of power system, it likely causes serious transient energy accumulation in the section, and power system will lose stability. Simulation and analysis on WEPRI-36 system verify validation of the proposed method.关键词
