电网损耗分析及降损措施的研究
摘要:安全和降损是电力企业的两大主题,实际配电系统中的线损水平是衡量和考核供电企业生产技术和经营管理水平的一项重要综合指标,有效降损也是提高企业经济效益的重要手段和有效途径。线损管理是供电企业的一项重要工作。对配电网进行线损计算可以发现配电网络运行的薄弱环节,了解损耗的构成,有针对性地采取合理的降损措施。本文从实际需要出发,在介绍线损理论计算方法与降低线损的管理和技术措施的基础上,结合实际配电系统进行了线损分析和研究,并提出了针对该配电系统降低线损的技术措施和改进方案,对提高供电企业的经营管理水平和经济效益具有明显的理论和现实意义。
本文首先对线损计算方法进行了研究,然后介绍了降低线损的管理措施和技术措施,并与实际运行情况相对照,提出了降低该系统线损的具体措施。

Power loss and loss reduction of research
ABSTRACT
For electric utilities, security and reducing line loss are the main concerns,and the line loss is an important techical index for assessing their technique and management levels ,moreover,in practical operation reducing line loss is also an effective measure and approach for improving the economic benefits .The weak aspects in the operation of the power work and the constitution of the energy losses can be found by calcuating the energy losses, so that the relevant reasonable measures can be adopted for reducting the energy at reducing line loss,and then proposes a scheme that is based on a practical project in author is utility and adopted practical parameter and data .The validity and merit of this scherne and the cost of power supply are proved.
This paper discusses the origin of line loss and its analyzing pares .The theory using for analyzing line paper proposes some particular measures and approaches for reducing the line loss of this practical work.
Keyword: power system,line loss analysis,measure for reducing line loss
