Comprehensive three-state data measuring and control device for intelligent transformer station

The utility model discloses a transformer station comprehensive measuring and control device which is suitable for an intelligent transformer station and a conventional transformer station and has the function of steady, dynamic and transient data acquisition and treatment. The measuring and control device adopts a multi-module structure and comprises a measuring and control module, a station control layer Ethernet communication management module, a process layer Ethernet communication management module, two FPGA modules responsible for high-speed data treatment and exchange and a colorful liquid crystal display management module. The transformer station comprehensive measuring and control device can be used for signal alternating current sampling of a conventional transformer and digital sampling of an electronic transformer and control output and digital output of a conventional relay as well as conventional state quantity signal input and digital input. The device simultaneously can be used for high-speed acquisition and treatment of steady, dynamic and transient data and reduce the equipment type in the transformer station, thereby simplifying the design and the construction of the transformer station and providing a uniform data source for an automatic power system.
