A whole-bypass U-pipe high-pressure feed-water heater system of a 300MW unit is taken a the subject investigated. The changing rules of the main characteristic parameters under two different types of faults, “water pipe leakage of heater”and “short circuit between a heater抯 inlet and outlet water-room”,and analyzed and summarized through detailed fault simulation tests with a full-scope power station simulator.Because the interaction of the heaters and the systemic effect between the heater system and other parts of the unit are fully considered,the changing rules for the characteristic parameters under the two different faults gotten through simulation tests are more reliable and close to the actual operation condition.

With the numerical simulation based on modern computational fluid dynamics method (CFD), the influence of the number of cars (length), train pipe system and its leakage on air-charging pressure of train pipe and the pressure distribution along train pipe in longitudinal direction are studied. We have established the continuity equations under train pipe leakage condition and presented an explicit finite difference method to solve the pressure-velocity coupling equations. The numerical results have been compared with the related test data of heavy haul train brake application of China and foreign countries. The research work has provided theoretical reference to study the experiments of brake application effects of heavy haul trains, and has paved the way for researching complete numerical simulation of freight train air brake system.
