摘要
The increase of wind power share increasing has lead to operational challenges for its integration and impact on power grids. Regarding this, unexpected dynamic phenomena, such as oscillatory events around 13Hz, among different wind farms were recorded in the United States Oklahoma Gas & Electric. Such interactions differ from traditional inter-area oscillations, and the ability to detect them is the beyond measurement capabilities of most of existing measurement equipment and monitoring tools in energy management systems. This article presents the development and implementation of algorithms for fast sub-synchronous oscillation detection, focusing on the aforementioned case. It proposes a real-time monitoring application that exploits synchronized phasor measurements, allowing real-time detection of sub-synchronous wind farm dynamics. This tool was built as a prototype for real-time application and utilizes phasor measurement unit data for enhanced monitoring and control. The article focuses on the tool's design and its algorithms. Also, it will briefly present three approaches carried out for testing and validating the phasor measurement unit based application, one of which compares the proposed tool with an existing tool at Oklahoma Gas & Electric. Through such experiments, the tool presented in the article has been positively validated for real-time applications.
