The safety and stability of the tailing reservoir play an important role in the mining production and environmental protection.

Some issues that require special consideration include the influences of UHV grid on the safety and stability,short circuit current,reactive power compensation,and structure of Fujian grid,as well as decoupling the 1 000/500 kV electromagnetic loop network,etc.

This paper introduces the study status of safety and stability problems for power systems at home and abroad, and it is very useful for electrical engineering reference.

Research on strategies of security and stability control system in Guangdong power grid;

Study on security and stability measures of the isolated grid operation of the Guizhou power grid and area power grids;

To improve the veracity and validity of power system dynamic simulation and ensure the security and stability of power system, it was proposed to add overspeed protection control model to simulation software.

It is researched whether if the security and stability performance of ultra high-voltage (UHV) grid could meet the requirements of power system security and stability criteria of China.

The security and stability of power system and the economic factors should be considered before breaking the electromagnetic loop circuit.

The security and stability under operation state is an important evaluation index to guarantee the safe operation of the monorail car.
