介绍一种新型的变电站电压无功综合自动控制装置。采用交流采样、变电站运行方式自动识别及跟踪适应、系统阻抗实时辨识、控制效果预测及软化边界控制等技术,利用工控机作为其核心,性能可靠,控制模型准确,控制原理先进,软件设计及硬件结构合理,能适应各种变电站自动调压和无功补偿设备的自动调整。在控制原理上,采用了主变分头和无功补偿设备综合调整的控制规律,提高了控制的合理性。该装置已在河南电网西沙口110kV变电站投入运行,结果表明,它完全适应现场运行要求和调节控制。该装置研制课题日前已通过省局组织的专家鉴定,专家们一致认为,其成果具有国内领先水平,且具有推广使用价值。
A new type of substation voltage and reactive power integrated automatic control device is introduced. Using AC sampling, automatic identification and tracking of substation operation and adaptation, system impedance real-time identification, control effect prediction and softening boundary control technology, the use of IPC as its core, reliable performance, accurate control model, advanced control theory, software design and hardware Reasonable structure, can adapt to a variety of automatic substation voltage regulator and reactive power compensation equipment automatically adjust. In the control principle, using the main transformer variable compensation and reactive power compensation equipment to adjust the control law to improve the control of the rationality. The device has been put into operation in Xishakou 110kV substation of Henan Power Grid. The results show that it is fully adapted to the on-site operation requirements and regulation control. The device research project has recently passed the provincial bureau of experts identified, experts agreed that the results have the leading domestic level, and has the promotion of the use of value.
