STATCOM对双馈入直流系统运行特性的影响
Impact of STATCOM on the Operating Characteristics of Double-infeed HVDC System
摘要
Abstract
Static synchronous compensator (STATCOM) can control the reactive power independently and improve the voltage stability of power system. The STATCOM was implemented at the inverter side AC busbar of double-infeed HVDC system. The model of double-infeed HVDC system included STATCOM was developed, then the derivation of mathematical model for the steady-state power transmission equations were deduced. By theoretical analysis and simulation in PSCAD/EMTDC, a few factors, included short-circuit ratio (SCR)、electric distance between two HVDC links, were considered to study the system performance. Increase in maximum available power (IMAP) was proposed to analyze the impact of STATCOM on the MAP when the SCR was different. The results show that STATCOM can equivalently increase strength of AC system fed by the DC subsystem, thus increase the stable operation area, improve commutation failure immunity and restrain the transient overvoltage of the DC subsystem, then effectively improve the steady and transient state operation performances of double-infeed HVDC system.关键词
