【摘要】 本文以舟山HVDC系统实际情况为例,探讨了逆变侧如何实现频率调节以及和整流、逆变两侧其它调节器在运行方式上如何配合。对于频率的测量方法、系统常见运行方式的数学模型,以及采用积分分离式的PID控制算法以期获得较好的动态和稳态性能做了研究,并给出了软件编程框图。更多还原

【Abstract】 Taking Zhoushan HVDC system as an example, the paper discusses how to realize frequency adjusting in an inverter and how the converter cooperates with the inverter in the operating mode. The method for measuring the frequency and the mathematical model of HVDC system in the common operating mode are also investigated. In order to achieve better performance, the PID control method of separable integral and program charts are presented.更多还原
