The invention discloses a subway power dispatching system power flow simulation method based on a traction calculation result. The method comprises the steps of enabling a PSCADA system and a tractioncalculation module to interact traction calculation information in a file form; establishing a traction calculation model and a traction load distribution model in the PSCADA system; enabling the PSCADA system to provide traction calculation parameters for the traction calculation module and obtains a traction calculation result from the traction calculation module; forming a simulated running chart for a period of time according to a traction calculation result and a running chart compilation method, and simulating distribution of traction loads; and combining the traction load distributionresult at a certain moment with the traction power supply system network model of the PSCADA system to carry out load flow calculation simulation analysis of the PSCADA system. According to the method, the space-time distribution of the traction load is simulated by the traction calculation result and the simulation running diagram, and the power flow calculation simulation analysis in the PSCADAsystem is realized in combination with the PSCADA system traction power supply system model, so that the calculation and analysis capability of the PSCADA system is greatly improved.
Description
Technical field [0001] The invention relates to the field of subway power dispatch, in particular to a power flow simulation method of a subway power dispatch system based on traction calculation results. Background technique [0002] Train traction calculation studies the related problems of train running along the track under the action of external force. For subway power supply system, train traction calculation can simulate the relationship between train current, train position and running time during train operation. Use the results of traction calculations and the method of operating diagram compilation to generate simulated operating diagrams to simulate the temporal and spatial distribution of trains on the traction network. [0003] The current subway power dispatching system (PSCADA) only realizes the monitoring and control of the subway power supply system, and has not yet realized the power flow analysis function of the entire power supply system. One of the important r...
