1MJ/0.5MVA/10kV SMES测控系统研究

Development of Measurement and Control for 1 MJ/0.5 MVA/10 kV SMES

主要研究超导磁体系统的检测方法、2kV脉冲磁体的过压、过流和失超保护方法、系统的故障诊断方法及其与SMES系统的协调控制方法。并研制了一台超导磁体系统的测控装置,应用于1MJ/0.5MVA/10kVSMES示范工程,通过系统挂网运行检验了其设计的合理性。

In this paper, the measure method of the HTS magnet and cryogenic subsystem is designed, the 2 kV pulse magnet is protected on the condition of over-current, overvoltage and quench, the failure diagnosis method of the system is explored and for the application of the SMES that used in a 10 kV bus of substation, a novel monitoring system based on the 485 series bus is designed. The circuit structure, control-strategy and the operation principle of the monitoring system are explained and analyzed in detail. The experimental results proved the validity of this system.
