Simulation evaluation method for configuration scheme of safe automatic device of transmitting-end power grid high-frequency cutting machine

The present invention provides a high-frequency cutting machine simulation evaluation method of Automatic safety device is configured to send the end of the program, comprising: establishing a frequency simulation data model comprising transmitting end grid unit and the grid side control related frequency side important element; set the sending end grid electric power in the level of basic research operating point; assumes DC block chain cutting machine automatic safety devices operate correctly calculated one by one for each basic research operating point failure in the form of two kinds of outgoing end of the grid feed channels, to obtain the sending end grid the simulation results; assumed DC block chain cutting machine automatic safety devices refuse to move, one by two kinds of outgoing channel failure modes the transmitting side is calculated for each basic research operating point grid, to obtain the sending end grid simulation results; according to step C and step D the obtained simulation results to evaluate the effect of high frequency cutting machine automatic safety device configuration scheme is good. The assessment method has rapid, accurate and comprehensive consideration, simple and easy operation, with high practical value.
