摘要
量测配置问题主要包括量测类型、量测地点和量测数量的选取,从量测类型的选择问题出发,针对配电网络完全可观的要求,构建配电网量测系统布置的算法模型,来确定量测地点和量测数量,使得量测达到成本最小化的目标。在量测系统的基础上,结合具体的IEEE14节点网络,根据具体的电力系统状态估计算例对该量测系统的评估指标进行检验和优化,来验证量测系统的有效性和正确性。
The problem of measurement configuration mainly includes the types of measurement, the location of measurement and the quantity of measurement. Based on the selection of measurement types, an algorithm model of distribution network measurement system layout is established to determine the measurement location and measurement quantity for the requirement of integral observability of distribution network,making the measurement to achieve the goal of minimizing costs. On the basis of this measurement system model, combined with the concrete IEEE14 node network, the evaluation index of this measurement system is tested and optimized according to the specific power system state estimation example to verify the effectiveness and correctness of the measurement system.
