提高電力系統穩定的措施

發布日期:2022-04-17 點擊率:85

  提高電力系統穩定的措施分為暫態穩定和動態穩定。

  提高暫態穩定的措施

  ①用快速保護和快速斷路器把故障切除時間減少到0.1~0.15秒之內;

 ?、趯⒐收舷拗圃诠收蠀^段內;

 ?、塾米詣又睾祥l盡快恢復網絡結構;

  ④自動切除水輪發電機組和快速關上汽輪機的汽門,以減少加速能量;

 ?、莶捎镁€路故障聯動切機或切除其他線路,以防止連鎖反應而擴大事故;

 ?、薏捎秒姎庵苿雍涂刂蒲a償設備;

 ?、呖刂曝摵晒β?如煉鋁廠),切除部分負荷,以及控制直流線路的功率等。

  提高動態穩定的措施

 ?、賹τ诰W絡結構不合理的系統,應增加線路回路數,發電機接入高壓主網以增強系統聯系;

  ②對于網絡結構一定的情況下,合理配置電力系統穩定器,改善大型發電機快速勵磁調節系統的參數和特性;

 ?、劭刂浦绷骶€路的功率,以提高并列運行的交流線路的動態穩定性等。
