近年来 ,随着科技投入力度的不断加大 ,供电部门先后建成了局域网 ,对调度自动化主站系统和变电所二次监控、电能计量表计等设备进行了升级改造。因此 ,更好地开发利用新设备的各项功能 ,发挥现有自动化设备管理电网、监视电网、控制电网的作用 ,是既减少重复投资 ,又提高经济 In recent years, with the increasing investment in science and technology, the power supply department has built a local area network, upgraded and transformed the dispatching automation master station system and substation secondary monitoring, electric energy metering meter and other equipment. Therefore, to better develop and utilize all the functions of new equipment and make full use of the existing automation equipment to manage the power grid, monitor the power grid and control the power grid, it not only reduces duplication of investment but also improves economy
