在理论分析的基础上,介绍了电压无功控制装置(VQCⅡ+)的硬、软件设计及实际应用。VQC-Ⅱ+采用新型结构,充分考虑到算法的可实现性及装置的向下兼容性,并具有良好的开放性,不但可针对具体工况灵活配置,而且扩展方便。同时,通过外围通信接口可与调度中心连接。当系统由分散控制转为集中控制时,同样可利用装置的远传、遥控等功能,配合新系统使用。 On the basis of theoretical analysis, the hardware and software design and practical application of VQCⅡ + are introduced. VQC-Ⅱ + adopts a new structure, fully taking into account the achievability of the algorithm and the backward compatibility of the device, and has good openness. The VQC-Ⅱ + can not only be flexibly configured according to a specific working condition, but also have a convenient expansion. At the same time, through the peripheral communication interface can be connected with the dispatch center. When the system from decentralized control to centralized control, the same can be used device remote, remote control and other functions, with the new system.
