安全经济是电网运行的主要目标。但是,自然灾害、人为失误和电力设备的不可靠性等事故隐患时常会给电网造成威胁。因此,防患于未然和在故障发生后及时予以排除,这在工程实践中就具有极为重要的意义。采用计算机实时监测电力设备,可提早 Safe economy is the main goal of grid operation. However, accidents such as natural disasters, human errors and unreliability of electrical equipment often pose a threat to the grid. Therefore, take precautionary measures and eliminate them in time after the failure, which is of great significance in engineering practice. Using computer real-time monitoring of electrical equipment can be earlier
