考虑用户行为及户均容量优化的配变容量规划

配电网是连接输电网和用户之间的关键部分,而在配电网规划过程中,配电变压器的规划又是其中的关键。目前配变容量的规划一般将重点放在负荷预测以及经济性上,缺乏对于用户用电特性和户均配变容量的分析,这使得规划结果可能不能满足负荷需求。为解决上述问题,提出了一种考虑用户行为及户均容量优化的配变容量规划方法,从负荷特性、用户数目以及负荷总量等方面分析用户行为并计算出配变的经济运行区间,并在对户均配变容量进行分析的基础上对配变容量进行优化,利用上述规划方法对实际配电网的配变进行规划,算例结果证明了有效性和实用性。

Planning of Distribution Transformer Capacity in Consideration of the User Behavior and Opti mized Capacity Per User

Distribution network is a key part of the connection between transmission network and users.In planning process of the distribution network,planning of the distribution transformer plays the key role.Current planning of distribution transformer capacity generally puts the key point on load prediction and economy with the lack of analysis on electricity characteristics and distribution transformer capacity per user which makes the planning results fail to meet the load demand.To solve these problems,we propose a planning method for distribution transformer capacity in consideration of the user behavior and optimized capacity per user.The user behavior is analyzed in terms of load characteristics,the number of users and the total load and the economic operation range of the distribution transformer is calculated and the distribution transformer capacity is optimized based on the analysis of the distribution transformer capacity per user.When the above method is applied to a planning of distribution transformers in a practical distribution network the result demonstrates the effectiveness and practicality of the method.
