摘要
随着江西电网的第一条特高压直流输电工程——雅中—江西±800kV特高压直流输电工程及1 000 kV特高压赣江变电站的建成,标志着江西电网特高压时代的进一步推进。同步调相机具有优异的暂态无功补偿性能,能减缓特高压直流线路接入后带来的受端交流系统冲击。因此,必须详细验证特高压直流输电系统加装同步调相机对电网的作用。文章以特高压鄱阳湖换流站为例,通过调相机涉网试验仿真,验证了同步调相机良好的动态无功输出能力。
With the completion of the first UHV DC transmission project,the Jiangxi Power Grid—Yazhong-Jiangxi ± 800 kV UHV DC transmission project and 1 000 kV UHV Ganjiang substation,it marks the further advancement of the UHV era in the Jiangxi Power Grid.The synchronous condenser has excellent transient reactive power compensation performance,which is able to mitigate the impact at the receiving-end AC system after the UHV DC line is connected.Therefore,it is necessary to verify carefully the effect of installing additionally synchronous condenser in UHV DC transmission system on the power grid.Taking the ultra-high voltage Poyang Lake converter station as an example,the paper verifies the good dynamic reactive power output ability of the synchronous condenser through the network-related simulation test of the synchronous condenser.
