Abstract

The invention relates to a communication management method, device and system for a high-voltage chain static var generator. The method includes: creating a Modbus data packet sending thread, a serial port thread and an Ethernet thread in the lower computer; creating a lower computer configuration file; the Modbus data packet sending thread reads the configuration file to obtain a Modbus instruction frame; the serial port thread reads the configuration file , to configure the serial port, receive the Modbus command frame of the Modbus data packet sending thread and read the Modbus command frame address, the serial port thread writes the Modbus return data into the shared memory, and notifies the Modbus data packet sending thread to read the next Modbus frame data ; Communicate with the host computer through the Ethernet thread. The invention realizes remote control, multi-parameter convenient input and human-computer interaction through the Modbus data management and the underlying data reproduction technology, and can transmit across networks.

Description

technical field [0001] The invention relates to the field of communication between a high-voltage SVG and a host, in particular to a communication management method, device and system for a high-voltage chain-type static var generator. Background technique [0002] High-voltage SVG is a high-voltage chain-type static var generator. During the research and development period, there are equipment safety issues, and close-range operation is more dangerous. If a serial line is used as a communication line, the performance is relatively good in terms of distance and anti-interference. Poor, so we can convert serial data to Ethernet data in-place. Ethernet communication can use network cables for data transmission. If equipped with a dispatch room, a router can be used as a relay to realize remote operation, avoiding the danger of operation. [0003] In the power system, the reactive load not only increases the active power loss of the grid, but also seriously affects the power q...
