Cibatu34-Mandirancan is one of the most important subsystem in Jawa Bali system. Peak Load of this subsystem is about 1.700 MW, several industrial costumers are also located here. On 13th March 2014 disturbance occured on Indramayu-Kosambibaru. This disturbance was followed by tripping of two transmission lines and all generators in Indramayu Power Plant. Disturbance Fault Recorder (DFR) data showed...
A novel construction method of decentralized systems for bulk power system is proposed. Firstly, a bulk power system is exactly rewritten into a one-machine one-load decentralized system by the power flow calculation at each generator-bus, and the one-machine one-load system with a middle load is also rewritten into an equivalent system without the middle one. Next, a three-machine and a longitudinal...
Based on the transient energy function (TEF) theory with classical models considered, the optimal re-closing time (ORT) can be calculated accurately. This paper mainly focuses attention on the validity and practicability analyzing of ORT obtained from this method. Firstly, the characteristics and influencing factors of the ORT are put forward and analyzed, and also the setting strategy of re-closing...
Evolutionary Programming incorporating neural network (EPNN) is proposed to obtain the solution of Transient Stability Constrained Optimal Power Flow (TSCOPF) in this paper. Evolutionary Programming (EP) is selected as a main optimizer while the neural network is a supplementary tool to enhance the computational speed by screening out individuals, which have very high or low degrees of stability....
The re-closing time of a transmission line has a distinct influence on power system transient stability. There is an optimal re-closing time (ORT) for all transmission line faults, no matter the instantaneous fault or permanent one. Based on the transient energy function (TEF) theory with classical models considered, the ORT can be calculated accurately. This paper mainly focuses attention on the...
