Abstract

The invention relates to application of computer simulation in an electric drive control system under a brake working condition of an electric-wheel truck, in particular to a method for simulating theelectric drive control system under the brake working condition of the electric-wheel truck. Under the power brake working condition, the control system consists of a wheel motor control part and a main generator control part, wherein the wheel motor control part calculates to obtain characteristic curves of excitation current and armature current according to related data, analyzes the working logic under the brake working condition, obtains characteristic curves of various links such as URS-Imf*, V-Imf*, V-Ia*, Imf*-Imf, and B-1 / R, and combines the power brake characteristics of the wheel motor to establish a simulation map of a wheel motor part under the power brake working condition in a Simullink environment; and the main generator control part establishes a simulation map of a maingenerator part under the power brake working condition in the Simulink environment by combining the main generator structure according to a main generator control schematic diagram. The method verifies the correctness of a scheme by comparing a simulation result and a demand characteristic curve of the system.

Description

technical field [0001] The invention relates to the application of computer simulation in the electric transmission control system under the dynamic braking condition of the electric wheel vehicle, in particular to a simulation method of the electric transmission control system under the dynamic braking condition of the electric wheel vehicle. Background technique [0002] Electric wheel vehicles are ideal and efficient transportation equipment in large-scale open-pit mines at home and abroad, and play an extremely important role. Its electric transmission adopts the STATEXIII type control system of GE Company of the United States. This system can control the car in real time, and through the online dialogue of the notebook computer, the relevant running data of the car can be obtained. [0003] However, it does not reveal the control structure of the system under dynamic braking conditions, so that users and researchers of the system cannot know the logical relationship of ...
