摘要
10 kV中压接线模式的选择受负荷密度、投资、可靠性等因素影响,是配电网规划与改造的关键。在不同负荷密度条件下,根据接线单元的供电能力确定所需数量。考虑多种因素对接线模式的投资成本和可靠性影响,结合用户停电损失综合函数,将可靠性与经济性进行属性转化。为了得到Pareto最优解,以影响接线模式的经济性、可靠性的线路参数建立初始种群,采用遗传算法(GA),以供电总成本最低为目标,获得任意负荷密度下的Pareto最优解集,从而建立中压接线模式的GA-Pareto优选模型。该理论已应用于中部某城市,为该市配电网建设提供理论依据。
The selection of 10 kV mid-voltage connection modes,which is the key to planning and transformation of distribution network,is affected by load density,investment,stability,etc.Under the condition of different load density,the connection unit capacity determines the required quantity.Considering the impact of many factors on investment cost and connection mode reliability,and combining the comprehensive function of user’s power outage loss,the economy and reliability can be transferred between each other.The line parameters which impact the economy and reliability of connection mode are adopted as the initial group,the genetic algorithm is used,and the power supply’s lowest total cost is taken as objective,to obtain the Pareto optimal solution set of any load density.Thus the GA-Pareto optimization model is established for mid-voltage connection mode.The model has been applied in a city in the central China,which supplies theoretical basis for the construction of distribution network of this city.
