Study on stable cutting strategy for isolated network of Nujiang power grid

提出了怒江孤网稳定运行策略。首先对怒江孤网运行时的电压、频率以及功角稳定性进行了分析,然后对孤网电力平衡进行了研究,制定了孤网运行的高频切机稳定策略。通过6轮切机策略,对孤网功角稳定,频率稳定以及电压仿真分析可以得到,怒江电网孤网能够稳定运行,同时进行电压调整使得怒江电网电压不越限。

This paper puts forward the stable operation strategy of the isolated network. Firstly, the voltage, frequency and power angle stability of the isolated network are analyzed. Then, the power balance of the isolated network is studied, and the stability strategy of the high frequency cutting machine is established. Through the 6 wheel cutting strategy, the stability of the power angle of the isolated network, the frequency stability and the voltage simulation analysis can be obtained, the isolated network of the Nujiang power grid can be operated stably, and＇the voltage adjustment makes the voltage of the Nujiang power grid not limited.
