摘要
本文以定子电压综合矢量恒定为控制约束，建立了变速恒频发电机的矢量控制模型，并由此对电机稳态和动态性能进行了理论分析和数值仿真。分析结果表明，转子交流励磁电流实行矢量控制的变速恒频发电机具有传统电机难以比拟的优良性能。
Variable-Speed Constant-Frequency (VSCF) generator with vector control for rotor exciting current is investigated. Both control model and control configuration implemented by an 8098 single-chip microprocessor are given. Accordingly,steady-state analyses are performed,and dynamic performance are analyzed by numerical simulation. Results show that a decoupled systm with soft-connection between mechanical side and electrical side is possible and high-performance and fast response can be achieved. When the time of control cycle is less than 100μs, the response period will be limited in the range from 1 to 3 ms.
