Abstract: A synchronous condenser exhibits operational characteristics similar to those of a generator, effectively enhancing system short-circuit capacity and rotational inertia. It possesses excellent leading phase operation capability, with dynamic reactive power output reaching up to twice its rated capacity. Furthermore, it is minimally affected by system voltage fluctuations and asymmetric faults, demonstrating superior dynamic regulation performance. The commissioning of a distributed synchronous condenser serves as a comprehensive test of the condenser equipment itself, protection and safety automatic devices, lubricating oil and cooling water systems, and other subsystems. It provides essential baseline data for the reliable operation of the condenser once integrated into the power system, holding significant importance for grid security and stability. This paper systematically discusses the commissioning process and technical key points for distributed synchronous condensers, aiming to provide a complete technical approach and practical reference for the commissioning of small-capacity synchronous condenser units.
