特高压交流变电站母线短路电流的影响因素分析
|
摘要
从特高压交流变电站高、中压侧母线等值自阻抗的组成要素出发,分析确定了特高压变电站母线短路电流的影响因素,给定了特高压变电站1 000 kV侧交流电网结构、特高压交流变电站主变压器以及500 kV侧交流电网结构对高压侧和中压侧母线短路电流影响的比重关系。分析结果表明,特高压交流变电站高压侧母线的短路电流主要受1 000 kV侧交流电网结构的影响,而中压侧母线短路电流主要受500 kV侧电网结构和特高压站主变压器的影响。研究结论可为特高压交流站近区电网限流措施的优化提供理论支撑。
The affecting factors of short-circuit currents of 1 000 kV and 500 kV bus-bar at UHV AC substation are analyzed based on the components of corresponding self-impedance. And then the proportions of all factors to the short-circuit currents at 1 000 kV bus-bar and 500 kV bus-bar are proposed and determined, including the configuration of 1 000 kV power grid, the main transformer and the configuration of 500 kV power grid. The results indicate that the short-circuit currents of 1 000 kV bus-bar are greatly affected by the configuration of 1 000 kV power grid. The 500 kV power grid and the main transformer have a dominant influence on the short-circuit currents of 500 kV bus-bar at UHV AC substation. The results can provide theoretical support and decision-making reference for the optimization of short-circuit limit.
