Synthesis Control Algorithm for Parallel Synchronous Generators of Marine Power Plant

简要地介绍了并联运行的同步发电机组之间有功功率、无功功率分配的调节原理,提出了基于微型计算机控制系统的船舶电站功率分配的数字PID(Proportion-Integral-Derivative)控制解决方案,通过优化数字PID控制算法二次调节发电机组,达到并联发电机组功率分配平衡的目的。经过试验、试验数据分析以及实际应用,证明该数字PID控制算法解决方案有效地实现了并联运行发电机组之间合理的功率分配,保证了船舶电站同步发电机组之间长期、稳定、经济的运行。

The adjustment principle of power distribution among parallel synchronous generators is briefly introduced, and a computer-based PID control system specialized for power distribution of power plant is proposed. It is validated by practice that this system is able to achieve an appropriate power distribution among parallel synchronous generators so as to ensure their long-term, stable and economical performances.
