Fault Diagnosis Of The Electrical Power System

The electrical power system fault affects, the scope in a big way broad, the process is quick, set the very high request to the fault judgment and processing Requests accurately to make the judgment fast, takes the effective action rapidly, the isolation fault, restores the power supply, avoids the accident expanding. The article has analyzed the system fault power flow characteristic, uses method splitting node piecemeal power flow technology, application principle of superposition and multiple port technology, establishes the electrical network fault condition model, through the fault analysis expert system, carries on the fast fault judgment the theory method. The article elaborated systematically through the data acquisition, the information filtration and the information fusion, the information modeling, digital simulation, technologies and so on, carries on the online real-time track computation to the electrical network operation, establishes the digital operation electrical network. And in this foundation, uses the artificial intelligence technology, the fast accurate diagnosis equipment, the fault type, the fault phase, the fault position, provide the fault most reliable direct evidence information; The prompt reminder operation personnel processes, and gives the processing suggestion.
