Selection strategy of substation distribution unit based on management collaboration theory

Area of Science:

• Electrical Engineering
• Asset Management
• Operations Research

Background:

• Traditional substation equipment selection relies solely on life cycle cost, which is insufficient for modern power grid demands.
• Increasing complexity in power grid development necessitates more comprehensive equipment selection strategies.

Purpose of the Study:

• To develop an improved equipment selection strategy for substations that incorporates multiple critical factors beyond cost.
• To enhance substation operational efficiency and support infrastructure development in power grids.

Main Methods:

• Enterprise Asset Management (EAM) for data preprocessing.
• Life Cycle Cost (LCC) analysis for economic evaluation.
• Reliability-Centered Maintenance (RCM) for reliability assessment.
• Rough Set Theory (RST) for energy efficiency evaluation.
• Collaborative Management Theory from Total Productive Maintenance (TPM) for the final strategy.

Main Results:

• The proposed strategy effectively addresses comprehensive development needs for substation operations.
• Validated effectiveness of the new selection strategy using historical data from a 110 kV substation.
• Demonstrated improvement in equipment selection beyond traditional economic considerations.

Conclusions:

• The developed strategy provides a robust framework for selecting substation distribution equipment.
• Offers theoretical support for the upgrade and renovation of substations, particularly in regions like Henan Province.
• Highlights the importance of integrating asset management, reliability, and efficiency in equipment selection.
