Automatic voltage control substation system of distributed power station based on devices

The invention discloses an automatic voltage control substation system of a distributed power station based on devices, which is suitable for automatic voltage control of a power system in the power station. The substation system comprises an automatic voltage control (AVC) workstation, a coordination control device and a plurality of execution control devices. For the convenience of on-site monitoring, a tablet computer is configured as an on-site operating panel. The invention fully meets the requirement of automatic voltage control of a high voltage bus bar in the power station, and has the characteristics of high universality, high reliability and high control accuracy. The invention realizes a high voltage bus bar voltage control function of the AVC substation in the power station, is suitable for the fields of thermal power, hydroelectric power, nuclear power and wind power, and supports a communication mode and a direct acquisition mode for acquiring real-time data required. In terms of hardware, the invention adopts industrial embedded devices and the design of power supply redundancy, controller redundancy and dual network redundancy, and in terms of software control algorithms, the invention considers various security constraint conditions and improves the reliability and anti-interference function of the system.
