Aiming at the lack of comprehensive and effective monitoring measures for station level equipment of smart substation in unmanned environment, an equipment monitoring system for station level in smart substation is designed. The system provides a real-time monitoring on the hardware, software and core business process of station level equipment and also proposes a periodic dynamic variation polling strategy by using graphic and visual method to display the monitoring data. After that, it makes fault analysis and smart alarm to the monitoring data, and sends to the master station by alarm direct-transmission to achieve the comprehensive control and fault prediction to station level equipment remotely and locally. Finally, the deployment and effect of project application about this system are given. This work is supported by Science and Technology Project of State Grid Corporation of China (No. 52152016000Q).
