ABSTRACT

Power dispatching automation system is used to monitor the operation status of the whole power grid, so that dispatchers can take a comprehensive view of the overall situation, operate the whole network, and effectively direct the safe and economic operation of the power grid. It is an important means of dispatching modern power grid. Power dispatching automation system plays an indispensable role in the safe and economic operation of power system. Firstly, this paper discusses the necessity of network communication function transformation of remote control device at power plant terminal, then introduces the equipment status of remote control device at power plant terminal, puts forward the transformation scheme and communication mode of remote control device, compares each scheme, and finally expounds the problems that should be paid attention to in the process of transformation. Compared with the traditional front-end system, the network front-end machine has fast network signal transmission, large bandwidth, high reliability, less interference, and is not limited by the number of traditional protocol transmissions. The device has the characteristics of high measurement accuracy, fast data refresh, good anti-interference performance, strong adaptability and high cost performance, certain economic and theoretical value.
