Abstract
There are three types of power lines in the 10 kV distribution network in China, i.e., copper power cables, overhead power conductors and aluminum alloy power cables. It is necessary to give a comprehensive evaluation to choose the type of power line in some delicate practical engineering. This paper presents a life cycle cost (LCC)-based analysis method for the three types of power lines. An LCC model of the power line in the 10 kV distribution network is established, which considers four parts: investment cost, operation and maintenance cost, failure cost and discard cost. A detailed calculation model for the four parts is presented, and to calculate the failure cost, the Monte Carlo algorithm is employed to simulate the values of expected energy not supplied (EENS). Two practical 10 kV power line projects in Fujian Province in China were analyzed based on the proposed LLC model and corresponding developed software, which has helped the power company select the appropriate power line successfully.
Highlights
As we all known, the distribution network is one of the main sections of the power system and takes the heavy responsibilities of social and economic development
This paper aims to concentrate on the life cycle cost (LCC) of the 10 kV distribution lines and to compare the three types of power lines in two practical projects by quantitative analysis
The economic differences among the aluminum alloy cable, copper cable and overhead conductor are compared through two practical engineering projects in Fujian province in China by an LCC evaluation software we developed
Summary
The distribution network is one of the main sections of the power system and takes the heavy responsibilities of social and economic development. The 10 kV power lines play significant roles in the distribution network in China. Three kinds of distribution lines are used widely, including copper cable, overhead conductor and aluminum alloy cable. In China, traditional distribution power lines are almost all copper cable and overhead conductor. The application of aluminum alloy cables is becoming more extensive in the distribution network. The quantity of copper resources has been found in China to be about 89.72 million tons since 1949
