Application of SVCs by CenterPoint Energy to Address Voltage Stability Issues: Planning and Design Considerations

摘要

CenterPoint Energy (CNP) is in the process of installing two SVCs on its transmission system which serves the greater Houston, Texas metropolitan area. Extensive voltage stability assessment was performed to understand the problem and determine the optimum size and location of the SVCs. This paper presents planning and design aspects of the SVC installations. As part of the planning consideration, the fundamental problem, alternative solutions evaluated, selection of the preferred option and other reactive power issues are covered. Additionally, as part of the design considerations, the SVC configuration, control strategy and other design issues are discussed.
