Abstract

The invention proposes a power characteristic analysis method and device, and the method comprises the steps: collecting historical electrical operation data in a preset time period, and generating ahistorical load curve according to the historical electrical operation data; collecting current historical operation data, comparing the current electrical operation data with the historical load curve, and generating a power characteristic analysis result according to a change trend determined through comparison. The method can reflect the dynamic changes of a power distribution network in a timedimension.

Description

technical field [0001] The invention relates to the technical field of power analysis, in particular to a power characteristic analysis method and device. Background technique [0002] In the power system, the analysis of power characteristics is the basic work of researching and analyzing the power market. It is related to the construction of the power grid and the planning of power supply. [0003] The existing power characteristic analysis methods can only characterize the static situation of power operation at a certain time section, and the operating state of the distribution network changes continuously with the passage of time. Dynamic changes in the time dimension have great limitations. Contents of the invention [0004] In view of the above analysis, the present invention proposes a power characteristic analysis method and device to solve the problem that the existing power characteristic analysis technology cannot accurately reflect the dynamic change of distri...
