摘要: 为了能够定量分析不同类型负荷对网损的影响,评估负荷用电结构变化后网损的变化趋势,提出基于边际网损系数法和代表日负荷曲线的不同类型负荷的网损计算方法。利用最大负荷利用小时数定量分析得到不同类型负荷与网损率的关系。以某市系统为例检验负荷用电结构改变对线损的影响,计算结果与定量分析结论一致;并结合大用户接入系统方案的优化对网损进行分析,验证所提方法的可行性和正确性。

关键词: 负荷, 用电结构, 边际网损系数, 负荷曲线, 网损分析

Abstract: For quantitative analysis of the impact of different components of power consumption structure on transmission losses, the trend of transmission loss caused by power consumption structure change was evaluated and a calculation method of transmission loss of different types of load representing daily load curves was proposed based on the marginal loss coefficient method. The relationship between different types of load and transmission line loss rate was given through qualitative analysis of the maximum load utilization hours. A case study of a city’s power system proves the feasibility of the presented method and the correctness of the conclusions.

Key words: load, power consumption structure, marginal loss coefficient, load curve, transmission loss analysis
