对可关断器件阀运行试验等效性进行研究,研究内容包括试验方法、方法的实现和试验等效性的分析3部分,其中试验方法包括试验对象的确定、阀应力分析及应力数学模型的建立、试验要求和试验内容的研究和等效试验方法的研究。以基于由IGBT组成的模块化多电平换流器(modular multi-level converters,MMC)阀的柔性直流输电装置稳态运行试验为例,对MMC阀的稳态运行试验方法、试验电路和试验等效性分析等内容进行研究,验证了等效试验方法的正确性。
Research on the equivalence of the valve run test of the shutdownable device includes three parts: the test method, the realization of the method and the equivalence test. The test methods include the determination of the test object, the analysis of the valve stress and the mathematical model of the stress Establish, test requirements and test content research and equivalent test methods. Taking steady-state operation test of flexible DC transmission based on modular multi-level converters (MMC) valve made of IGBT as an example, the steady-state operation test method, test circuit and test of MMC valve Equivalence analysis and other content research, verify the correctness of the equivalent test method.
