Abstract: As an important reactive power regulation unit supporting the stable operation of ultra-high voltage direct current power grids,large-capacity new-type synchronous condensers require real-time operating condition monitoring to ensure unit safety and reliability. Aiming at the technical limitations and complex system structure of existing imported monitoring devices, a domestic chip-based TSI system is developed based on an independently controllable software and hardware platform. The device adopts an integrated architecture integrating protection and monitoring, supports the access of multiple types of sensors, and possesses highly reliable diagnosis logic and protection strategies. This paper elaborates the overall design scheme, hardware configuration and fault diagnosis strategy of the proposed system. Fault injection tests verify the accuracy and responsiveness of the TSI system diagnosis. The system has been applied in practical converter station projects, and its functions and performance have been fully validated in engineering applications.
Key words: synchronous condenser; TSI system; independently controllable chip; self-diagnosis; multi-type sensor
