摘要
直流输(配)电是目前电网发展的趋势,而高压直流断路器的研发是影响其发展的关键技术之一;测量与控制装置的研究是高压直流断路器的研发要点;采用高压电力电子器件,DSP+FPGA相结合的控制方式,对其测控装置进行研究分析,提出了区间阈值的控制方法及相应的控制时序,从高压直流输电、能源多样化的发展需求入手,将机械开关和固态开光相结合,设计了一套混合式高压直流断路器样机;通过对样机进行合分闸试验及故障分闸试验,证明了所研制的高压直流断路器样机具有分闸动作快,限弧能力强,动作一致性好等优点。
The current trend of development is DC input（with）electric power grid.However,the development of HVDC circuit breaker is one of the key technologies.The research of the measurement and control device is the key point of the development of high voltage DC circuit breaker.It designed a prototype hybrid HVDC circuit breaker,which use the high-voltage power electronics,and the controller of DSP＋ FPGA combination.It researched the monitoring device,and proposed the control method of threshold interval and the control timing.It designed a prototype hybrid HVDC circuit breaker,which form the high-voltage direct current transmission,energy diversification,the development needs of combining mechanical switch and solid medallion.Through the prototype sub-gate opening test and fault tests proved that the developed prototype HVDC circuit breaker with the fast opening operation,the advantages of good action consistency etc.
