| Resumo: | Title screen The electric power system elements are designed to transmit electricity to consumers. To ensure the transmission, in the design and construction of the power system provide for increased cross-section of lines, throughputs of transformers, cost for other procedures. To find the magnitude of the increase, it is necessary to determine the maximum power flow through the element. This is important for the digital substation operation, where all actions are subordinated to the automation elements, and the ability to control power flows, through the electrical equipment management, has the primary task. This solution is not absolutely effective, since it's not known how much the measures are related to the accident probability. It's needed to know where the maximum power consumption can appear. Therefore, it is necessary to determine in a non-deterministic form how the available power plants power is distributed over the grid to ensure power supply. The main problem is that obtaining the probabilistic characteristics of the parameters by standard statistical methods has no practical solution. In this regard, the method of selection of interval boundaries of input and output data (SIBD) is proposed, and its application for obtaining probabilistic characteristics of electrical quantities and their imbalances. |
