500kV同塔4回线在RTDS上的仿真建模

Simulation modeling of 500 kV four-circuit tower lines by RTDS

针对华东电网将要建设梅里—利港、梅里—泰北的500 kV同塔4回线,介绍了在RTDS实时数字仿真系统上完整创建的同塔4回线仿真模型和分析,并与EMTP电磁暂态计算结果进行了比对分析,结果表明,该系统能够真实反映500 kV同塔4回线路各点电压、电流、频率、相位角等电气量特性,完全具备进行华东电网“泰北—梅里—利港”同塔4回线路相关控制保护设备的完整闭环试验条件。

To study the Meili-Ligang and Meili-Taibei 500 kV four-circuit tower lines that will be built within East China Power Grid, the simulation modeling of the four-circuit tower lines by the Real-Time Digital Simulator （RTDS） is analyzed, and the simulation result is compared with the result of calculations conducted by Electromagnetic Transients Program （EMTP）. It is showed that the characteristics of voltage, current, frequency, and phase-angle of the four-circuit tower line can be truly reflected by RTDS, and the RTDS is well equipped to conduct complete closedloop tests of control and protection equipment for the Meili-Ligang and Meili-Taibei 500 kV four-circuit tower lines.
