Abstract


A method is proposed for reducing the computation time while maintaining the stability of the simulation. Examines the joint modelling of objects and devices of relay protection and control. The complexity of the simulation increases when has many sites of a network, especially when real-time algorithms are designed for records in programmable chip devices. Volatility through modelling is associated primarily with the volume of inputs, intermediate and representative accumulated information. Reducing the computation time is necessary due to the exhaustion of a physical resource by clock rate and the effective number of computing processors. The relevance of objectives is maintained in conditions of continuous improvement of the element base of devices, software, technological equipment, and requirements for construction of electric power networks. The method is based on the formation of a semantic signal, which compresses the parametric information on order times. It is shown how the selection of semantic signal in each device will allow known control tasks on the network to be resolved. Shows how to solve problems through simulation of devices taking into account the semantic information flows. For this proposed method of improving the algorithms works on the basis of mutual correspondence of the two equivalent generalized block diagrams of object control and devices for relay protection and control. The obtained quality indicators simulation. Examples of improvement of devices in the task of building high voltage networks for smart-grids with a Petersen’s coil are presented. The results are useful for solving problems of the information ‘throat’, diagnostics ‘not under stress’, and automatic restoration of the sense of emergency files for mobile, stationary and outsourcing jobs.
