This paper took the check of rupturing capacity circuit breaker in petrochemical electric power network for example. It introduced the selection rule of largest short-circuit current which flow through circuit breaker, the principle of short circuit calculation, the equivalent model of external system, the modeling of mathematical model of industrial electric owned power network, and the procedures...
Structural features has been analysed after the third part of SINOPEC Tianjin company's power system been put into operation. Node voltage been treated as the constraint, minimum power loss been treated as the objective function, used PSASP to calculated the different way of generator's combination, the voltage , power flow, power loss has been compared before and after the OPF calculation. The conclusion...
The dynamic frequency characteristics of industrial electric power network is Analyzed when external faults occurs. It reveals the active power gap, adjusting effect parameters and other related factors how to affect the frequency. Appropriate model is build about Tianjin Sinopec Company. Power transition process under external faults is simulated by PSASP. It proves the correctness of the conclusions...
