The paper contains description of an automated control system of 35 kV and higher power networks, developed by the BNTU in collaboration with research-and-production firm «Dipol» and introduced at «Minskenergo» power networks. The description of algorithms for solution of some technological problems realized in the library of applied programs that presents a calculative nucleus of the given developed system. Connection procedure of the developed applied program library to the operative and measuring complex of the automated system is given in the paper.Описываемся автоматизированная система управления электрическими сетями напряжением 35 кВ и выше, разработанная в БИТУ совместно с научно-производственной фирмой «Диполь» и внедрённая в элект...
