Problems solved by technology

Since RTUs are usually embedded devices, the development of functional modules is difficult, and the implementation is relatively complicated. Moreover, expanding a task module with relatively complex functions will definitely occupy the resources of the RTU, which may affect the original tasks of the RTU.

Embodiment Construction

[0037] The technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0038] The present invention proposes an automatic voltage control system with wide adaptability, high flexibility and strong safety based on the actual configuration of on-site automation equipment in power plants. Its specific content is as follows:

[0039] 1, figure 1 It is a schematic diagram of the frame structure of a substation of a power plant according to the present invention. As shown in the figure, the sub-station of the power plant is composed of main host computer, standby host computer and lower computers 1, 2, ..., k. As the decision-making center of the entire substation, the upper computer also conducts information exchange through its own communication plug-in and the telecontrol communication device on the site of the power plant with standard communication protocols. Both the upper computer and the lower computer hav...
