摘　　要：针对独立供电系统中异步化同步发电机的参数设计问题。依据柴油发电机组中异步化同步发电机的数学模型及最优化理论,使用坐标方式下降法和空间角度二分法下降法相结合的搜索方法进行参数优化。参数优化结果表明:考虑到异步化同步发电机外形尺寸的约束及输出电能质量的要求时,在规定的转差率范围内发电机主要感抗值变化不大;复励变压器的感抗优化值随转差率的增大而增大,并且是在确定的区间内变化。For parameter design method of the asynchronized synchronous generator in independent power supply system, the parameter optimization is made by combination means of the coordinate descent method and the spatial angle dichotomy method based on the mathemati- cal model and the optimization theory of the asynchronized synchronous generator in a diesel- generator sets. The following features are proved by the results of parameter optimization. First and foremost, the major inductance of the generator changes little within the specified slip scope when the constrained size of the generator and the requirement of output power quality are considered. Second, the optimized inductance of the compound excitation transformer increases with increasing of the slip, moreover it changes within a determined range.
