Research on Selection of Servo Control System for Compressed Air Energy Storage

In the demonstration project of compressed air energy storage with power 10MW, choosing the correct servo control systemum is reliable guarantee for precisely controlling generator speed and power. By the comparison of different servo system, such as pneumatic, electric, and hydraulic servo control system, and the requirement for adjustment performance and security of units, and the reference of demonstration project which has been put into operation, pneumatic servo control system of gas open type is the most appropriate solution.
