Adaptive damping controller is a challenging issue in the area of power system stability and control because of the difficulties in identification and design in real system. In this paper, a heuristic adaptive HVDC supplementary damping controller (AHDC) is designed based on online Prony analysis. Parameters of the controller are tuned according to the damping ratios of the weak-damped inter-area...
Synchronized phasor measurement technology has been gaining increasingly interests in China due to its wide area time synchronization capability and fast transmission speed. Over 10 years of implementation of wide area measurement system (WAMS) in Chinese power grid have shown its great value in power system dynamic monitoring and potential applications in system modeling and validation, feedback...
Wide-area measurement system (WAMS), based on technology of synchronized phase measurement, can precisely measure real-time dynamic information of power network. It will provide new methods that achieve real-time control, stability enhancement and transfer capacity improvement in power network. WAMS constructed in Jiangsu power network, includes several PMU substations, data concentrator and central...
According to the plan of several power grid administrations, the substation of 220 kV and above voltage level and power plants with capacity of 300 MVA and above will be covered by PMUs in order to establish a nation-wide dynamic measurement system. PDC will cover provincial grids and area grids. PDCs are to be interconnected to form a nation-wide interconnected dynamic measurement system. Synchrophasors...
