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...
The condition of thermal power plant of some SINOPEC is simply introduced first, after choosing its receiving operation, enterprise internal power's dynamic frequency characteristic mechanism has been analyzed under external fault condition, and then arriving at a conclusion that the dynamic frequency characteristic has something to do with active power shortage and frequency adjustment effect modulus...
