This paper proposes an online calculation method of theoretical power losses for high-voltage(HV) distribution system based on rapid modeling and data quality analysis in order to improve the timeliness, accuracy and efficiency of the important task. At first the power grid structure model can be rapidly formed according to the basis data library transferred from the original PSD-BPA format file....
A model of FACTS based high voltage short circuit current limiter(HV-SCCL) applicable for electromechanical transient simulation of large power grid is established with the user-defined program of PSASP software, which developed by China Electric Power Research Institute(CEPRI). Through comparing periodically line current and its variation rate with the corresponding short-circuit current (SCC) threshold,...
This paper presents a new algorithm for rapid estimating inter-area oscillation(IAO) mode shapes and corresponding modes using correlation analysis(CA). It firstly extracts a weak damping component strongly associated with objective mode from each tie-line active power signal came from WAMS(Wide Area Measurement System), through a low-pass or band-pass filter which is designed by a priori modal knowledge...
This paper establishes a model of HV-SCCL for electromechanical transient simulation using user-defined program of PSASP software. This model decides whether or how thyristor protected series compensation (TPSC) would be switched on or off and consequently controls the capacitive reactance value, through comparing periodically line current and its variation rate with the corresponding short-circuit...
