Embodiment Construction

[0090] The present invention will be further described in detail below through the specific examples, the following examples are only descriptive, not restrictive, and cannot limit the protection scope of the present invention with this.

[0091] A power grid risk calculation method based on multi-source data fusion, characterized in that it includes the following steps:

[0092] 1) Multi-source information data fusion: integrate the ledger data, user data, operation data, geographical information, risk factors and other data of each business system of the power grid to obtain a complete power grid model including the fused multi-source information data;

[0093] 2) Set the expected accident set: the feeder in the power grid model is used as the unit to establish the expected accident set. Any equipment failure under any feeder is an expected accident cycle until all equipment fails once, and the expected accident set is obtained;

[0094] 3) Power failure analysis: For the ex...

Abstract

The invention provides a power grid risk calculation method based on multi-source data fusion. The method comprises the following steps: multi-source information data fusion: fusing machine account data, user data, operation data, geographic information, risk influence factors and other data of each business system of a power grid to obtain a complete power grid model comprising fused multi-sourceinformation data; setting an anticipated accident set; analyzing power loss; carrying out load flow calculation; and risk calculation: calculating a transformer area risk and a feeder line risk according to the obtained fault analysis data. According to the power grid risk calculation method based on multi-source data fusion, the calculation processes of data fusion, accident anticipation, load flow calculation and risk calculation are achieved, the power grid risk level is accurately evaluated, weak links are found out and improved, and therefore the power supply safety of the power grid isimproved.

Description

technical field [0001] The invention belongs to the field of electric power. More specifically, the present invention relates to a power grid risk calculation method based on multi-source data fusion. Background technique [0002] With the development of the national economy and the improvement of people's living standards, the requirements for the power supply capacity, power supply quality and power supply reliability of the distribution network are getting higher and higher. The existing urban distribution network has weak links such as weak grid structure, outdated power equipment, serious line overload, and low level of distribution automation. Therefore, it is necessary to analyze the weak links of the distribution network, and put forward corresponding improvement measures for the weak links to improve the reliability of the distribution network operation. [0003] The existing risk calculation method is to study the system reliability level in the case of expecte...
