Post-evaluation model for 500 kV substation engineering projects using the fuzzy comprehensive evaluation method.

Area of Science:

• * Power Systems Engineering
• * Project Management
• * Economic Evaluation

Background:

• * Comprehensive economic evaluation is crucial for 500 kV power transmission and substation projects.
• * Existing evaluation methods may not fully capture the complexities of these large-scale infrastructure investments.

Purpose of the Study:

• * To develop and apply a post-evaluation model for 500 kV power transmission and substation projects.
• * To assess the economic benefits and overall outcomes of a specific 500 kV project.
• * To provide data-driven recommendations for improving future project management and sustainability.

Main Methods:

• * Fuzzy Comprehensive Evaluation (FCE) method integrated with the Analytic Hierarchy Process (AHP) and Delphi method.
• * Development of tailored scoring criteria for qualitative and quantitative indicators.
• * Aggregation of expert opinions and empirical data for a holistic assessment.

Main Results:

• * Overall project success score of 92.54 out of 100.
• * Outstanding performance in planning effectiveness (100.00), preliminary achievements (99.12), and construction performance (98.00).
• * Perfect scores (100.00) for social and environmental impacts, but lower scores for economic benefits (61.88) and financial performance (54.33).

Conclusions:

• * The developed FCE model provides a robust framework for evaluating complex power projects.
• * While the project excelled in non-financial aspects, significant improvements are needed in economic and financial performance.
• * The study offers valuable insights and practical guidance for enhancing the management and economic viability of future power transmission and substation projects.
