Embodiment Construction

[0080] Power system design mainly refers to the matching design of power system parameters. Power system parameter matching design (also known as hardware parameter design, power system / assembly parameter design) refers to the system A series of processes of reasonable matching design and optimization of parameters. Its main task is to reasonably determine the characteristic parameters of each power component such as the power and capacity of the engine, motor, and battery. Different from traditional rail transit vehicles, hybrid rail transit vehicles have a complex structure and complicated internal energy flow. Therefore, establishing a set of feasible characteristic matching optimization design theory has become the key to the matching design of hybrid rail transit vehicle power system.

[0081] The parameter matching design of the hybrid power system has a significant impact on the power performance, economy, environmental protection and even engineering feasibility of the...

Abstract

The embodiment of the invention discloses a vehicle-mounted fuel cell hybrid power system designing method. The method comprises the steps of obtaining tramcar line designing parameters, vehicle design parameters, running index parameters, fuel cell parameters, monomer power battery parameters and super capacitor module parameters; calculating needed power and needed energy of a hybrid power system under a dynamic cycle running condition according to the parameters; inputting the parameters, the needed power and the needed energy into a fuel cell hybrid power system design optimization model;solving a Pareto non-dominated solution set of control variables of the fuel cell hybrid power system design optimization model; constituting a Pareto leading edge according to the Pareto non-dominated solution set and target function values corresponding to the Pareto non-dominated solution set. In this way, a reference design scheme for designing the fuel cell hybrid power system which meets user requirements is provided for design personnel. The embodiment of the invention further discloses a vehicle-mounted fuel cell hybrid power system designing device.

Description

technical field [0001] The present application relates to the technical field of fuel cell hybrid power applications, in particular to a design method and device for a vehicle-mounted fuel cell hybrid power system. Background technique [0002] Urban traffic congestion and environmental pollution caused by vehicle exhaust emissions have become a problem that plagues every large and medium-sized city. The development of urban public transportation, especially urban rail transit, and the application of new energy are an effective way to solve urban congestion and air pollution. The national "Twelfth Five-Year Plan" clearly states that the country will focus on the development of technologies and equipment such as large-capacity high-speed transportation and new energy transportation, and orderly promote the construction of urban rail transit such as subways, light rails, and trams. Therefore, urban rail transit based on new energy has become a national key development directi...
