Control Measures of Shanghai Power Grid Short-circuit Current
Shanghai power grid is at the end position in the East China Power Grid, it is one of the highest load density load centers in the East China, even around country. As an integral part of the entire East synchronization grid, short-circuit current of the Shanghai power grid has a great relationship with southern Jiangsu and northern Zhejiang. Therefore we can use the following methods to control short-circuit current of the Shanghai grid; take strict control of power access system; adjust the system structure and operation mode; installation of series reactor; installation of short-circuit current limiter;high impedance transformer; the development of effective higher-level voltage grid, and have a wider range for grid optimization in the East China region.
