The Research And Development Of Test Platform On Excitation Test Based On Virtual Instrument

The excitation experiment before the generator incorporation is an extremely important link. At present, the traditional test equipment very difficultly has carried on the comprehensive accurate test to the excitation system with each aspect characteristic, it adapts the modem technology development request with difficulty. Therefore, the new excitation experiment measuring instrument with complete development function and simple operation is imperative.This article established a test platform based on the hypothesized instrument excitation experiment, to construct the excitation experiment metering equipment With the hypothesized instrument is domestically in still the number advanced technology.This article careful has conducted the research to main algorithm in the excitation system test platform. Tests the platform hardware was constituted through the PC-DAQ way, with graph programming language -LabVIEW7.1 took the software development platform, which has completed the hypothesized instrument test system. The test platform can do the field test,Carries on gathering, analysis, processing, and demonstration to the electricity parameter data, obtains the test result report. It be uses to inspect the quality and the control characteristic of excitation installment, which guaranteed the generator incorporates reliable investment and reliable movement. In the hardware circuit design, this article in detail elaborated the sensor choice, the signal conditioning extensions, the data acquisition card ,and the measure antijamming should adopt. In the software design, it has carried on the front panel and the flow chart design using LabVIEW7.1. Moreover, this article conduct the development research to tekecommunications of test system.
