Abstract

The invention discloses a managing and monitoring system for direct current of a transformer neutral point. The system comprises a server side and a plurality of client sides in logic connection with the server side, wherein the server side comprises a data transceiving subunit, a comprehensive service subunit, a WEB service subunit, a display unit and a plurality of acquisition units; each client side comprises a central management subunit; besides, the server side is connected with a message transceiving device through a serial port. According to the managing and monitoring system for direct current of the transformer neutral point, the efficiency is high, intellectualization is realized, and the direct current condition of the transformer neutral point can be monitored and recorded in real time; monitored and recorded data can be effectively subjected to statistical analysis, and a statement can be formed regularly, so that the distribution rule and the influence degree of an influenced transformer in a covered area can be mastered and monitored, information management of yearly monitored data is facilitated, and effective accumulation, search and sharing of the monitored data are realized.

Description

technical field [0001] The invention relates to the field of transformer neutral point direct current monitoring, and more specifically relates to a transformer neutral point direct current management and monitoring system. Background technique [0002] With the rapid development of modern science and technology, according to the current test and operation practice, when the direct current transmission system is transferred from normal operation to unipolar-earth circuit operation or bipolar unbalanced operation, the DC current in the earth It will flow into the transformer winding through the neutral point grounding wire of the transformer and invade the AC system. [0003] Among them, when the DC current flows into the transformer winding, it will cause the DC bias of the transformer, which will increase the noise and vibration of the transformer, increase the loss, and degrade the voltage quality. However, there is currently no dedicated technical system for real-time mo...
