| 摘 要： | 随着高压直流输电技术的发展和西电东送规模的扩大,将会有越来越多的高压直流输电线路和换流站投入运行.当高压直流单极运行时,其大地回路直流电流会影响500 kV交流变压器的运行,例如:变压器噪音明显增大,出现过热现象,甚至引起变压器损坏.惠州电网目前有1个换流站,2个500 kV变电站,直流单极运行时会对该2个变电站的变压...

| Abstract: | More and more HVDC lines and DC-AC converter substations will be put into operation due to the advancement of HVDC technology and the larger scale of the West-to-East power transmission project.When a HVDC system operates in monopole mode,some problems such as significant noise rise and overheating occur in 500 kV AC transformers,or even some transformers would be damaged.There are one DC-AC converter substation and two 500 kV transformer substations in Huizhou power grid.The transformers in the two substat... |
