摘　　要：本文介绍了一种以数字信号处理器(DSP)为核心的,双CPU同步发电机励磁调节器,集监测、分析、控制、保护于一体,克服了国内励磁装置自检测、自保护的不足[1],使装置可靠性得到了大大的提高。并在研究机组并网的无功负荷调差分配的基础上,给出了该数字调节器在电力系统中的建模与仿真,仿真结果表明:调节器模型能够满足同步发电机和电力系统的各项运行要求。This paper introduces the research on the Excitation Regulator of the Synchronous Generator with dual CPUs, based on Digital Signal Processor （DSP）. With the multiple functions of monitoring, analysis, controlling and protection, it overcomes the shortage of the domestic excitation device in terms of self-monitoring and self-protection, which effectively improves device reliability. By analyzing the allocation of reactive load of the interconnected Synchronous Motor group, the modeling and simulation of the digital excitation regulator in the power system are illustrated in the paper. The results of the simulation show that the proposed regulator model is feasible, satisfying various running demands of the Synchronous Motor and Power System.
