Research On Life-Cycle Management Of Electric Substation’s Construction Quality Management

Substation is one of the important components of the electric power system. It is important for power allocation, scheduling and transport controlling. Substation quality has a decisive influence on power quality of the overall system performance. And its quality directly affects on the economy, security, and reliability of substations. How to guarantee the substation quality from design to operation during the whole life cycle is one of the most important problems. So the power grid enterprises need to pay close attention to the quality issues.This article first analyzes scope, content and characteristics of substation quality management in China. According to the characteristics, we define the management responsibilities within the life-cycle. The internal and external reasons for quality problems are given out. Due to the transformer substation project construction quality of design and construction quality, quality service is to operate in the end. So the entire life cycle and overall quality management is the required substations to meet quality requirements for power allocation, scheduling, and traffic control. This paper stands at height the system theory with the life-cycle perspective to analysis the quality problems. Even though the management people and the management points are total different, the finally goal is provide sustainable and high quality electricity. The third chapter details the life-cycle model of total quality management of substation connotation and management methods. Then from the point of application of the method, extract substation design, construction and operational phase of main quality control points, to help the quality management department or staff for detailed quality control. Then the early-warning index system of quality management is established to find quality problems and the solutions earlier. At last, expansion project demonstrates the implementation method and the validity of life-cycle and total quality management methods. This paper provides a theoretical reference for the quality management of electric power enterprises in China.
