智能变电站二次操作校核方法研究

随着我国智能变电站的快速发展,智能变电站的二次安全措施也受到了更多的关注。智能变电站在运维过程中,需要安全可靠地隔离二次设备,以免影响电网的安全稳定运行。因此,提出了二次设备的状态概念,采用数学建模方式,描述二次设备不同状态(如运行、检修等)之间的转移,最后提出了基于逻辑计算的二次操作校核数学推理方法,并通过模拟算例验证了此数学推理方法的正确性。

Research on Checking Method of Safety Operation in Intelligent Substation

With the rapid development of Smart Substation in China, the secondary safety measures of Smart Substation have also received more attention. In the process of operation and maintenance of smart substation, it is necessary to isolate secondary equipment safely and reliably in order to avoid affecting the safe and stable operation of power grid. Therefore, this paper puts forward the concept of secondary equipment state, and models the transfer of secondary equipment between normal state and abnormal state in a mathematical way. On this basis, a mathematical reasoning method for checking the operation of Ancuo based on logical calculation is proposed. The correctness of this mathematical reasoning method is verified by two examples, Yongdeng Change and Mozhugong Card Change.
