摘要

对于 300Mva$r$ 同步冷凝器，使用静态变频器将其从 0 启动至额定转速的 1.05 倍，以便在预定时间内并网。根据制造商提供的 300Mvar 冷凝器型式试验参数，分析了启动过程中的损耗，并将其转换为阻力矩。设计了启动过程中不同阶段的驱动扭矩曲线，以实现对启动过程的最佳控制。提出了计算 SFC 容量的方法，使 300Mvar 同步冷凝器的启动时间满足要求，并通过工程项目验证了 SFC 容量计算方法的正确性。

Capacity Calculation of Static Frequency Converter for 300Mvar Synchronous Condenser

For the 300Mva$r$ synchronous condenser, the static frequency converter is used to start it from 0 to 1.05 times of the rated speed for grid connection under pre-determined time. Based on the type test parameters of 300Mvar condenser provided by the manufacturers, losses during startup process is analyzed and converted into resistance torque. The driving torque curve is designed to have different stages of the startup process for best control of the process. A method is put forward to calculate the SFC capacity so that the startup time of 300Mvar synchronous condenser shall satisfy the requirement and the correctness of SFC capacity calculation method is verified by engineering projects.
