大扰动下电力系统惯性时空分布特性的表征形式初探
A Preliminary Research on the Representation Form of Spatial-temporal Distribution Characteristics of Power System Inertia Under Large Disturbances
摘要
Abstract
Most studies on the spatial-temporal distribution of system inertia(SDSI)have focused on inertia estimation.Meanwhile,the representation of the concept of system inertia is not unified and lack the in-depth analysis of its characteristics and the systematic sorting and analysis of related concepts.This paper attempts to explore the representation form of the SDSI characteristics under large disturbances.The SDSI characteristics is analyzed based on frequency dynamic process analysis.The concept of quantity of system nodal inertia is proposed and its characteristic description parameters are given.A quantitative analysis method of these parameters is proposed based on the physical mechanism of inertia and the difference calculation formula of the correlation coefficient is derived.A simulation example is given to verify the analysis and judgment of the SDSI characteristics,which can be characterized comprehensively and normally by the proposed representation form.关键词
