Static Security Analysis Applies in the Network of SINOPEC Tianjin

It is of great significance for us to research security problems in the power system. After choosing static security, related theories and methods to be main research object, we calculate power flow and use transferring load as safety countermeasures for power restoration at the same time. Here, we select the Newton method. Then, making the static analysis module of PSASP as the electric power system simulation software to apply in analyzing power flow and N-1 open circuit, which is under the biggest operation in petrochemical system. At last, we get related overload information in order to inspect whether the operation method and the connection mode of SINOPEC network is safe, and facilitate the ability of risking given accident, and take corrective actions at last.
