Step S1: the design of subsystem is decomposed: on the basis of fully considering model reusability, sub-system model level
Change, component module, and carries out system decomposition according to the topological structure of real system；It mainly can be there are two types of mode:
1) from top to bottom: for scale complex system, model is successively decomposed into several subsystems from top layer system, then
Subsystems are decomposed layer by layer.
2) from bottom to top: for single system, when needing to carry out modeling and simulating to element mechanism, needing the bottom to model
Element carries out functional analysis, models, then progressive from bottom, establishes system model.

It will illustrate the specific embodiment of the embodiment of the present invention by taking trailer system as an example below.
Fig. 4 is the structural schematic diagram of trailer system model library in one embodiment of the invention.As shown in connection with fig. 4, it is based on
The high-speed EMUs subsystem modeling method of Modelica model, may include following three parts content:
Step 1: the design of trailer system is decomposed；
Trailer system is responsible for taking from power grid supplying electricity to each system power supply of EMU, is the very important subsystem of EMU.
Trailer system is related to the technologies such as electro thermal coupling, electric control, is a sufficiently complex system.By the study found that traction system
System many elements feature having the same, according to the equipment of trailer system can by systemic hierarchial, each component module,
The element of different levels can be composed of next layer elements model.
For interface, such as preliminary filling electric model, four-quadrant rectifier model, inverter model generally comprise two power supplys
Anode interface, two power cathode interfaces and a hot interface, these two pair power interface form power supply dual-port, each moment electricity
Stream is flowed into from a pair of of interface, and another pair interface outflow, the energy that the energy of inflow is equal to outflow adds the energy of storage inside to add damage
The energy of mistake.Hot interface forms single interface, allows hot-fluid one-way flow for connecting with heat dissipation model.
As shown in figure 4, the trailer system can be decomposed into following a few major class: transformer mould according to electric circuit diagram design classification
Type, current transformer model, motor model；The current transformer model is divided into preliminary filling electric model, four-quadrant rectifier model, inverter again
Model etc., the element and physical equipment correspond.
Step 2: the trailer system model library based on Modelica java standard library is built；
For trailer system, how each physical component of system at model and is carried out with computer language description
It calculates and solves variable, be the key that model buildings.The model of math equation description is difficult to reflect that physical component is all completely
Physical behavio(u)r chooses principal element so needing to consider modeling requirement before building model from demand, ignores secondary cause, right
Model carries out a degree of simplification.This is usually the difficult point of modeling process.For trailer system, electro thermal coupling calculates can shadow
It rings and arrives entire simulation calculation speed, so needing suitably to simplify according to truth for thermal effect model, consider main production
Thermal element ignores the element of heat production very little.
Trailer system is modeled, can mainly there is following two mode:
1) it is modeled according to equipment physical principle；
Based on the model in Modelica java standard library, system model library can be built.Build model mode predominantly according to
According to the physical principle Direct Modeling of model, the model of each element is built with classical physical equation.The major part of this system
Element models accordingly, such as current transformer model.
2) it is modeled according to experimental data；
Since the physical principle that many equipment are related to is still not clear, do not come to a conclusion perhaps or too complex, it can be to setting
The standby method using experimental data modeling is modeled.By importing experimental data in pattern number table, computation of table lookup is carried out, both
Calculating speed is not influenced, and can be with the operation conditions of closing to reality equipment.Such as transformer model.
Step 3: the calibration of trailer system model library and verifying based on Modelica model；
For model user, the accuracy and authenticity that model calculates are most important.For trailer system
Calibration and verifying mainly by debugging the parameter value of each element, while needing producer to provide relevant technical indicator or production
Product parameter, the experimental data etc. of user are compared by calculated value with experiment value, and error is no more than such as 5%, illustrate model
True enough, calculated value can be with the physical behavio(u)r of reaction system.For example, the rotor voltage current curve of motor and measured curve are kissed
It closes, error is no more than such as 5%, illustrates that the motor model of trailer system and real electrical machinery are almost the same.
The method of the present embodiment, can multi-granule modeling meet the design verification requirement in each stage, while can be with
Meet the modeling and simulating of more physical fields, model reusability is high, can guarantee the precision that model calculates, and improves trailer system emulation
Modeling efficiency.
