Abstract
As an extreme contingency struck Kinmen island power system, it is very likely to cause blackouts. Although underfrequency protection scheme had been applied, some drawbacks of the scheme hinder Kinmen power system from avoiding blackouts. In the past one decade, several blackouts have occurred in Kinmen power system. To avoid blackouts, a special protection system (SPS) is summoned up. This paper describes the design and deployment of an SPS for Kinmen power system. The design depends upon Kinmen power system characteristics, and the deployment hinges upon supervisory control and data acquisition system (SCADA). Exquisite software is also developed to testify Kinmen system SPS. Operational record has been shown that the proposed SPS can save Kinmen power system from blackouts. Experience of design, implementation and operation of an SPS gained in this paper might interest protection engineers.
