- Abstract:
- The universal mathematical model of an engine is established, and an economical zone, in which an engine mainly provides medium output load at medium speed, is presented. Based on the experimental data and the universal model of such an engine above, a mathematical model of a refitted engine is provided. The boundary of the corresponding economical zone is further demarcated, and the optimal operating curve and the operating point of the engine are analyzed. Then, the energy transforming models of the power system are established in the mode of cooling, heating and power(MCHP), the mode of heating and power(MHP)and the mode of electricity powering(MEP). The parameter matching of the power system is optimized according to the transmission ratios of the gear box in the power distribution system. The results show that, in the MCHP, the speed transmission ratio of the engine to the gear box(ies)and the speed transmission ratio of the motor to the gear box(ims)are defined as 2.9 and 1, respectively; in the MHP, when the demand load of the power system is less than the low critical load of the economical zone, the speed transmission ratio of the motor to the engine(ime)is equal to 1, and when the demand load of the power system exceeds the low critical load of the economical zone, ime equals 0.85; in the MEP, the optimal value of ims is defined as 2.5.
