A new type of wide-area backup protection in power system
The theory and technology of relay protection need to be improved under the union of power systems.Thereby,a new scheme of wide-area backup protection is presented.The scheme takes an analysis from the whole power system to solve the problem of cascade trip in power system effectively and increase the stability of power system.The hardware is discussed,and design of the protection software including the software framework is detailed.
Summary form only given, as follows. A study is presented of precision constraints imposed by a hybrid chip architecture with analog neurons and digital backpropagation calculations. Conversions between the analog and digital domains and weight storage restrictions impose precision limits on both analog and digital calculations. It is shown through simulations that a learning system of this nature can be implemented in spite of limited resolution in the analog circuits and using fixed-point arithmetic to implement the backpropagation algorithm. >
