摘要(Abstract)：
根据电网发展规划,"十二五"期间浙江电网将出现1000kV特高压交流输电工程和±800kV特高压直流输电工程同时投产的盛况。为此,从电压稳定、频率稳定、功角稳定等方面考察浙江特高压交直流混合电网的系统稳定性,评估不同直流落点对系统稳定性的影响,发现了浙江电网暂态稳定的薄弱区域和薄弱点,绘制了浙江电网交流故障引发直流故障的概率分布图,提出了研究结论与建议。
According to the power grid development plan of State Grid Corporation,both 1 000 kV UHVAC and ±800 kV UHVDC transmission system will be put into operation in Zhejiang during 2011-2015.The paper evaluates the stability of Zhejiang UHVAC and UHVDC Power Grid,including voltage stability,frequency stability and power-angle stability.The effects of different locations of UHVDC inverter stations on the system stability are also analyzed.Weak areas and points of transient stability are discoverd and the probability graph of DC commutation failure caused by AC faults is shown.Finally,reseach conclusions and suggestions are given.
