Grid-connected full digital monitoring system for controllable high-temperature superconducting magnetic energy storage (SMES) system

Abstract

The invention relates to a grid-connected full digital monitoring system for a controllable high-temperature superconducting magnetic energy storage (SMES) system. The grid-connected full digital monitoring system adopts a dual-processor form based on a microcontroller and a digital signal processor (DSP) to realize the monitoring on the high-temperature SMES system in a grid-connected operation mode. A full digital man-machine interaction interface can display an instantaneous operating parameter and operating conditions of a power grid, an SMES magnet and a power regulator, and can display various fault information on a liquid crystal terminal interface for fault location and removal when the SMES system is failed in the grid-connected process. The digital man-machine interaction interface has a control command touch key for field personnel to control, namely, the touch key can be touched to control the operating condition of the power regulator; and meanwhile, remote control of an upper computer is supported. The invention comprehensively takes the conditions of the SMES system, the power grid and the power regulator and a necessary safeguarding technology into consideration. The grid-connected visual monitoring system with a man-machine interaction function for the SMES system can effectively ensure safe operation for the SMES units.

technical field

[0001] The invention belongs to the technical field of superconducting power application, and relates to a fully digital grid-connected monitoring system based on the second-generation high-temperature superconductor superconducting energy storage system (SMES), in particular to a controllable high-temperature superconducting energy storage system grid-connected full digital surveillance system. Background technique

[0002] The discovery of high-temperature superconducting materials in 1987 laid the foundation for the practical application of high-temperature superconductors. The low-temperature superconducting energy storage system is a relatively mature technology in the practical application of superconducting, but due to the high cost of refrigeration, it faces a bottleneck that cannot expand market applications. With the rapid development of high-temperature superconducting materials and modern power electronics technology, high-temperature superconduc...
