| Abstract: | 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. |
