Wide area measurement system (WAMS) has been widely used in power system dynamic monitoring and control, such as low frequency identification and control, stability assessment and preventive control, etc. However, as a measurement tool, phasor measurement unit (PMU) has the measurement error and bad data unavoidably. If the raw measurements are applied in power system analysis and control directly,...
Wide area measurement system (WAMS) has been widely used in power system dynamic monitoring and control, such as low frequency identification and control, stability analysis and control, etc. However, as a measurement tool, WAMS has the measurement error and bad data unavoidably. If the raw data is applied directly, the unpredictable consequence will be resulted in. Aiming at this problem, a novel...
Overhead transmission line is one of the basic elements of power systems, whose parameters are of great importance to the normal operation of the power system. Thereby how to acquire the accurate parameters of overhead transmission lines is crucial. In this paper a novel method to identify the transmission lines' parameters on-line is deduced, where the data from PMU/WAMS (phasor measurement unit/wide...
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...
