Latest Patents

Wangjun Zhang holds a patent titled "Method for state estimation based on the measured data of the data-acquisition system in power system." This method involves distributing measured data into an operating power system to create a calculation model. It defines the injection power of link nodes as zero and utilizes the maximum active and reactive power outputs of generators as constraints. The mathematical model constructed for estimation resolves the optimum solution for voltage amplitude and phase angle at each node. The estimated values of voltage, active power, and reactive power are calculated using these optimum solutions. The method is designed to be robust against bad data, thereby improving the correctness of the estimation process.
