摘要
广西壮族自治区能源资源缺乏,远期的电力缺口将主要考虑以直流的方式接受外区水电予以补充,而多直流并列运行将对电网的安全稳定运行造成一定影响。从分析广西电网远期电源建设空间入手,结合远景广西省内电源建设规划、外区受电规划以及分区电力流等情况,对广西电网接受直流的落点、远景规模以及相互影响进行了研究,并对多直流落点可能带来的电网安全稳定风险进行初步分析,初步判断广西远期具备接受多同直流落点的能力,但对各落点的接入方式还需进一步研究,研究结论可供电力规划参考。
In the long term, the energy shortage of Guangxi Autonomous Region will be compensated by outside hydropower energy from DC transmission. However, multi-infeed HVDC has impact on power system operation security and stability. Several problems related to multi-infeed HVDC system in Guangxi grid are analyzed based on power construction planning, power acceptance planning and current operation conditions. The problems include infeed system location, scale, mutual impact and possible risk on gird security and stability. Preliminary judgment indicated that Guangxi power grid has ability to accept Multi-infeed HVDC. However, further research is needed for the detailed connection scheme.
