Embodiment Construction

[0047] In order to better understand the present invention, the content of the present invention will be further described below in conjunction with the accompanying drawings and examples.

[0048] The present invention provides a distribution network reliability and economic benefit analysis method based on equipment abnormalities, and the method includes the following steps:

[0049] Step 1: Obtain the transaction information of the equipment in the power supply area

[0050] The equipment (asset) operation and maintenance lean management system (PMS2.0) is a unified equipment (asset) operation and maintenance lean management system for the operation and maintenance department, covering the operation and maintenance business and production management process. Realize the life-cycle management of equipment (assets) from planning, installation, operation, decommissioning, reuse to scrapping.

[0051] The PMS2.0 system records equipment (asset) change information, including eq...

Abstract

The present invention relates to a distribution network reliability and economic benefit analysis method based on equipment abnormalities. The investment cost is calculated by obtaining the abnormality information of the equipment in the power supply area, and the reliability investment is matched with the pre-arranged blackout event to obtain the association relationship. Describe the change information, establish the reliability improvement prediction model of the distribution network before and after the reliability investment and the calculation model of the economic benefit of the distribution network reliability investment, when the equipment in the power supply area changes, use the calculation model of the distribution network reliability investment benefit Calculate distribution network reliability investment benefits. The technical scheme of the present invention solves the problem of the source of investment data in the analysis of the reliability and economic benefits of the distribution network, and the problem that the reliability improvement of the distribution network can be obtained at the macro level through historical power outages and reliability investment data, and at the same time establishes A comprehensive distribution network reliability economic benefit analysis model can more accurately reflect the impact of distribution network investment on distribution network reliability.

Description

technical field [0001] The invention relates to an economic benefit analysis method, in particular to a distribution network reliability economic benefit analysis method based on equipment abnormalities. Background technique [0002] Studying the calculation and evaluation methods of distribution network reliability investment economic benefits is beneficial to power grid companies according to different reliability investment economic benefits generated by different investment levels, and to analyze the positive benefits, negative benefits, and comprehensive benefits of different distribution network construction and transformation. Evaluation and assessment. [0003] In order to establish a distribution network reliability investment benefit analysis model, reliable distribution network reliability and economic data sources are needed. At present, in the process of reliability management, power grid enterprises will record information such as the time of the power outage ...
