Abstract

The invention relates to a communication method of auxiliary equipment in a hydraulic power plant. The communication method is achieved according to the following steps: a serial communication interface of in-site equipment of the hydraulic power plant is connected to a serial port of a serial port network server, and an Ethernet port of the serial port network server is connected to a network switch of an upper computer system; an IP address of a port of the serial server is set, the serial server is adjusted to a TCP/IP SERVER mode, and a TCP/IP port number is set; an OPC server is arranged on an upper computer; a communication channel of the OPC server is configured according to the IP address and the TCP/IP port, communication protocols and data items are configured according to in-site equipment types, and communication connection is established; DX service is configured to achieve many-to-many data exchange; a public LCU is configured to write communication data into an upper message sending area; an upper computer database is configured, and alarm information and monitoring pictures of in-site equipment of the hydraulic power plant are visually configured to finish communication access of the auxiliary equipment.

Description

technical field [0001] The invention relates to a communication method for auxiliary equipment of a hydropower plant. Background technique [0002] With the development of smart grid, intelligent control equipment is required. Electrical products with communication control functions have become the focus of research and development of domestic and foreign electrical manufacturers. Low-voltage electrical appliances are developing towards networking and communication, and communication will become a new generation. The main characteristics of low-voltage electrical appliances. At present, the upper computer communication software of the company's computer monitoring system is not very open. If it is necessary to increase third-party equipment communication, the original manufacturer needs to write the driver program and debug it on site. First, the cost is high and the implementation cycle is long. Second, the customized communication program is not standardized. Therefore, i...
