Abstract
Because the long time's big power cut will create the huge economic loss and the bad social impact, therefore the black start will be all Electricity company very matter of concern. In recent years, along with the economic competition and marketability advance, the electrical power system was getting more and more close the stability limit movement, simultaneously system's scale and the complexity increased day by day, cause the system big power cut the risk to increase greatly. After big power cut, the request system can the fast reliable restoration, therefore the establishment order, the reliable black start plan is very essential. This article take the Northeast electrical network peaceful bay area black start plan as a background, to small was certain questions which in the integration link operating process met has carried on the analysis discussion, switched on the operation to same time to conduct the thorough research specially, simultaneously gathered the link operation using MATLAB and the PSCAD two kind of softwares to the black startup procedure to carry on the simulation computation. After the analysis comparison, has obtained time the generator and the system incorporation the condition which should satisfy in the peak-to-peak value and the initial phase angle aspect, restores in the breakdown in the actual operation has certain guiding sense. key word: Electrical power system; Black start; Gathers the link
