Abstract:To solve the problem of ‘blind spot’ existing in power distribution unit (PDU) and terminal distribution supervision in electric power information and communication equipment room, a holistic solution is proposed in this paper. It aims at online monitoring in terms of electrical parameters such as current, voltage, power, frequency, power consumption, switch state, lightning arresters and total harmonic distortion, as well as environmental parameters such as temperature, humidity, smoke and flooding. Thus, data has been displayed and queried realtimely, and then been uploaded to the superior visual monitoring system and remote duty system through the communication interface. Meanwhile, we can set the threshold alarm of any parameter as well as the prealarm. Though the pilot application, it has been verified that this solution can improve the reliability of power grid communication, and enhance the overall monitoring and operat of the electric power information and communication equipment room.
