Main electricity generator simulator for inner combustion locomotive

Abstract

The invention discloses a simulator of the main generator of a diesel locomotive. A serial communication circuit used for ISP in the simulator of the main generator of the diesel locomotive sends nominal parameters and boundary parameters of the main generator to a single chip through serial communication, the single chip collects field current signal of the main generator input by an analog quantity input circuit; and the output voltage and the current of the main generator are calculated by the mathematical model of the interior main generator thereof according to the diesel rotate speed signals and locomotive speed signals input by a frequency quantity input circuit, a digital quantity input circuit and locomotive condition signal, and output to a analog quantity output circuit. The device adequately simulates output voltages and currents of the main generator under various working conditions and load changing conditions, so that a control system of microcomputer controls the main generator of the diesel locomotive as well as the main generator is controlled on a locomotive. The invention has the advantages that the ground experiment can be realized before loading, the main generator is not required to be directly controlled, the cost is saved, and the device is economical and practical.

Description

technical field [0001] The invention belongs to an electronic simulation device, and mainly relates to a main generator simulator of an internal combustion locomotive. Background technique [0002] The main generator of diesel locomotive adopts AC synchronous generator. The main generator converts the rotating mechanical energy generated by the diesel engine into AC electrical energy, and then the main rectifier group rectifies the AC into DC for use by the driving device. The application of computer control technology to locomotive control is an important symbol of locomotive modernization. The main control object of the microcomputer control system of diesel locomotives is the main generator. It is neither realistic nor economical to directly control the main generator when the microcomputer control system is tested on the ground before loading. Therefore, there is a need for a main generator simulation device for a diesel locomotive, which can simulate the output voltag...
