摘要
分析了我国近年来电网线损率变化情况,通过对线损管理工作中经常遇到的综合线损率、分压线损率、理论线损率等问题的比较分析,认为由于跨区输电不断增大,按现行的行业标准计算的综合线损率不能有效地指导实际工作,需要修正综合线损率的公式,以加强线损管理。
This paper summarizes and analyzes the changes in the line loss rate that have been taking place in China these years. Based on a comparative study on the issues of the general line loss rate, the divided voltage line loss rate and the theoretical line loss rate which frequently occur in the practice of line loss management, it is concluded that the general line loss rate calculation based on the current industry standard can not provide effective guidance for engineering practice due to the continual growth of trans-regional transmission, and that it is necessary to amend the calculation formula for the general line loss rate so as to strengthen the line loss management.
