Semi-physical simulation test bench and test method for diesel-fuel combined multi-engine parallel operation device

Abstract

The invention aims to provide a semi-physical simulation test bed and a test method for a diesel-gas combined multi-engine parallel operation device. The semi-physical simulation test bed comprises a simulation diesel engine, a simulation gas turbine, a hydraulic dynamometer, an electric turbine dynamometer, a multi-shaft gearbox and a test bed monitoring control system. The simulation diesel engine and the simulation gas turbine are connected with a gearbox shaft through an SSS clutch, a torquemeter and a coupler, and then the hydraulic dynamometer and the electric turbine dynamometer are driven independently or jointly through the coupler and the torquemeter. According to the invention, semi-physical simulation of the diesel engine and the gas turbine can be realized, and the operation adaptability of the system under different working conditions is greatly improved. And meanwhile, monitoring control of each device of the test bench is realized, the controllability of the test bench is improved, the flexibility of the test bench is increased, and the test cost is reduced.

Description

technical field [0001] The invention relates to a semi-physical simulation device and method, in particular to a ship power semi-physical simulation device and method. Background technique [0002] With the gradual decline of global oil reserves and the stricter global emission regulations, green transportation has become the general trend. At present, the development direction of the automobile industry is shifting from fuel vehicles to hybrid vehicles and new energy vehicles, and cars are gradually becoming greener. In the shipbuilding industry, many shipowners are looking for a new power mode with low conversion cost, low operation cost and low maintenance cost. However, the actual effect of the new power mode cannot be predicted without testing and debugging, so experiments are needed to verify its reliability. [0003] However, the full physical test of the joint test run of the system not only has the problems of high cost and high risk, but also increases the risk o...
