Based on character of signal in TWACS and harmonic in power system, the digital differential technique can detect the TWACS signal and eliminate the integer harmonics effectively.
The harmonic balance method(HBM)was employed to solve the forced response of damped blades considering nonlinear feature of differential equations.
