互联电网运行控制性能评价标准研究:(二)新标准构架
摘要
从中国电网频率偏差的实际变化规律出发
基于概率理论的分析
讨论了不同时间尺度下的控制目的
进而明确了标准的设计思想
提出了一种新的互联电网运行控制性能评价标准构架。在该构架下
包含频率安全标准、无意交换电量标准和频率质量标准等3个标准
分别对应分钟、小时和月及以上3个时间尺度的控制性能评价。在新构架下所设计的标准
既可引导控制区域快速做出调节
为系统保证电网频率秒或分钟级时间尺度的频率安全奠定基础
又能允许控制区域在一定的时间尺度内“将功补过”
可解决目前中国各区域电网公司所实施标准中可能出现的频繁调节和过度调节问题
从而达到节能减排的目的。
Abstract
Based on the actual variation of the grid frequency deviation
the control purposes on different time scales are discussed according to an analysis of the probability theory. Then
the design idea is defined and a new control performance asssessment criteria frame of China’s interconnected power grid is proposed. There are three standards in this frame: standard of frequency safety
standard of unintended power exchange and standard of frequency quality. They correspond to control performance assessment at minute
hour
month and even above
respectively. The new criteria in the new frame can not only lead the control areas to make fast adjustment
but also lay the foundation for frequency safety on minute and second time scale. On the other hand
the new criteria allow control areas to use good performance to make up for mistakes within a definite time scale
solving frequent adjustment and overadjustment in regional grid companies of China to achieve energy saving. This work is supported by State Grid Corporation of China.
