【摘要】：电力系统的建设和扩大规模时需要兼顾均衡地利用电网中的电气设备,充分发挥已有资产的价值。本文以社会发展及电网建设裕度、配变供电半径情况、不同运行方式下的设备容载比等影响因素为基础,提出考虑配电网安全和运行方式的设备综合利用率指标和计算方法。通过设备综合利用率指标的分析并结合电网运行的薄弱环节的约束,提出一种考虑设备利用率的电网扩建改造方法,并给出了求解流程。该方法考虑配电网不同的运行状态和负荷情况,同时追求高效利用每个元件设备和尽可能均衡地利用所有元件设备。以某地配电网为例进行分析,验证了该方法的实用性和有效性。
[Abstract]:In the construction and expansion of power system, it is necessary to make balanced use of the electrical equipment in the power network and to give full play to the value of the existing assets. In this paper, according to the social development and the margin of power grid construction, the distribution transformer power supply radius is considered. On the basis of the influence factors such as the capacity to load ratio of the equipment under different operation modes, The comprehensive utilization ratio index and calculation method of equipment considering the safety and operation mode of distribution network are put forward. Through the analysis of the comprehensive utilization ratio index of equipment and the restriction of weak link of power network operation, In this paper, a power network extension and transformation method considering equipment utilization ratio is proposed, and the solution flow is given. This method takes different operation states and loads of distribution network into account. At the same time, the efficient use of each component equipment and the balanced use of all components and equipments are pursued. The practicability and effectiveness of this method are verified by an example of distribution network in a certain place.
