Design of AC Test System for On-load Tap Changer Based on High Speed Data Acquisition Card
摘要
Abstract
To improve the reliability and stability of a power grid, real-time monitoring of the core component in a transformer-on-load tap-changer (OLTC) is necessary. However, the conventional DC real-time monitoring system is deficient. As a result, an AC real-time monitoring method is introduced in this paper to make up the shortcomings of the DC monitoring system. In conventional data acquisition process, A/D converter is adopted, and the combination of sample-and-hold circuit and analog switch is employed to accomplish multi-channel data acquisition at same time. The authors use a high-speed data acquisition card, which is simple in both circuit structure and operation, for the multi-channel data acquisition. The real-time monitoring of OLTC is completed by developing a test software with Delphi. This test system is verified experimentally.关键词
