Abstract :
This paper summarizes the optimization methods of allocation optimization of power quality monitors (PQM) in the networked power quality monitoring system (NPQMS) and divides them into three categories. Utilizing one of them that takes the system average ambiguity (SAA) as valuation basis and considers some important factors, such as network topology analysis, weighting factor calculation and state estimation for no monitoring nodes, a new automatic locating method for power quality disturbance source (PQDS) in the NPQMS is presented with the definition of virtual PQM and extended matrix algorithm. A case study demonstrated the effectiveness of the proposed method.
