Abstract:
The uniform mathematical model of distortion signals in power grid has been setup with the theory of Wiener-G Functional. Firstly, the Matlab simulation models were established. Secondly, the Wiener kernel of power load was found based on the Gaussian white noise as input. And then the uniform mathematical model of the power grid signal was established according to the homogeneous of the same order of Wiener functional series. Finally, taking three typical distortion sources which are semiconductor rectifier, electric locomotive and electric arc furnace in power grid as examples, we have validated the model through the Matlab simulation and analyzed the simulation errors. The results show that the uniform mathematical model of distortion signals in power grid can approximation the actual model by growing the items of the series under the condition of the enough storage space and computing speed.
Key words: electric energy measurement distortion signals model of power grid signal functional series Wiener kernel
