针对常规电网换相换流器型高压直流阀区故障及直流系统测量隐患,文中提出了相应的定位方法。首先,根据晶闸管单向导通特性构造线性整流函数,再根据基尔霍夫电流定律构造对应阀区不同区域的差动电流,并进一步利用换流阀导通时序和现有保护减少误判,缩小划定的阀区故障范围。为查找直流系统测量隐患,构造量测方程并利用状态估计算法对测量值进行估计,并给出工程优化方法。实际故障案例和硬件在环试验结果表明,所提算法能够较为准确地定位阀区故障以及直流系统测量隐患。
Aiming at valve faults of conventional line-commutated converter based high-voltage direct current (LCC-HVDC) and hidden measurement defects of DC systems
this paper proposes the corresponding location methods. First
the linear rectification function is constructed according to the unidirectional conduction characteristic of the thyristor
and then the differential current corresponding to the different regions of valve area is constructed according to Kirchhoff current law. Furthermore
the conduction sequence of the converter valves and the existing protection are used to reduce misjudgment and narrow the fault range of the valve area. In order to find out the hidden measurement defect of DC systems
the measurement equation is constructed and the state estimation algorithm is used to estimate the measured values
and then the engineering optimization method is given. The actual fault cases and hardware-in-loop test results show that the proposed algorithm can accurately locate the fault in valve group and the hidden measurement defect of DC systems.
