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...
