Power-flow simulation with visualization function based on IEEE common data format <Abstract> In this paper, power-flow calculation simulator with its visualization function is proposed and implemented. Generally, it is necessary to prepare a text file, which describes power systems with generators and loads. This preparation is one of the barriers for power-flow simulations. The proposed simulator has a function of automatic generations of IEEE common data format file from user-drawn power-system diagram. Therefore, it is possible for users to make a simulation only by drawing power systems on display. In addition, the proposed simulator also has a function that power-system diagram is illustrated automatically from IEEE common data format file. By using this function, it is possible to visualize power flow amount and direction on the bus-system diagram, which helps for users to comprehend network dynamics intuitively. Because the proposed simulator allows including renewable-resource generators in the power system, it is useful to evaluate the power distribution systems. It is shown in this paper that the proposed simulator can make IEEE common data format file correctly and illustrate intuitive power-flow. |
