RESEARCH AND APPLICATION OF ELECTRICAL EQUIPMENT ONLINE CONDITION MONITORING BASED ON ELASTIC SLIDING WINDOW FFT
摘要
Abstract
The research and application of electrical equipment online condition monitoring based on 10ad feature is a hotspot.First, a model about the condition behavior of the electrical equipment based on FSA is built, which can describe the steady characteristics and transient characteristics effectively when the electrical equipment is running.Then, an elastic sliding FFT algorithm is raised, which solves the problem that traditional sliding FFT can only calculate the frequency spectrum under fixed frequency.Finally, the system prototype aimed at frequency spectrum feature realtime calculation according to this model which uses online monitor conditions of an electrical equipment is built and the result verify that the model and algorithm above-mentioned is effective.关键词
