摘要
Abstract
As one of effective measure to control power flow during power transmission, phase shift transformers (PST), which is also known as phase angle regulators (PAR), are widely applied in UHV power transmission grid abroad. Up to now the static phase shifter (SPS) technique has not been adopted in China and the result of the research on electromagnetic transient of SPS is seldom reported. A design scheme of UHV SPS, in which the thyristor-controlled step-by-step switching is adopted, is proposed. Using electro-magnetic transient simulator (EMTP) and taking typical power grid as example, the impacts of SPS on steady state operating voltage, power frequency overvoltage and switching overvoltage of UHV transmission line are analyzed. Analysis results show that after the installation of SPS the steady state operating voltage at the end of UHV transmission line rises slightly than without installation of SPS. The switching overvoltages caused by switching in/off UHV SPS as well as that caused by single-phase reclosure of transmission line, in which the UHV SPS is installed, are all within the allowed range specified by the standard.关键词
