Composite author of INRTU Department of Electric Power Stations, Networks and Systems of the Institute of Power Engineering consisting of professor Alexander VISYASHCHEV, associate professor Stepan TIGUNTSEV and PhD student Eduard PLENKOV secured a patent for invention issued by US patent office. The invention deals with the technologies aimed at power supply efficiency increase, and namely the way of locating a short circuit point in an overhead power transmission line by taking unsynchronized measurements at both ends thereof.
The invention relates to power industry and can be used for locating short circuits in power transmission lines by measuring the instantaneous current and voltage values when unsynchronized measurements are taken at both ends of the line. It is a technological object of the invention to improve the accuracy of damage location. This invention helps to decrease the delay period of electricity transmission to users in case of electrical network damage. The invention belongs to the priority field of science and technology development “Technologies for developing of energy-efficient systems of heat and electricity transmission, distribution and consumption”.
The new approach offered by the team of professor VISYASHCHEV helps synchronizing voltages and currents at the ends of the line when the measurements made at both ends thereof are not synchronized by aligning the oscillograms at the two ends of the line along the short circuit start section; improve the accuracy of damage location; and make the method practicable through the use of simple devices and methods, in the absence of complicated equipment and laborious calculations and complex mathematical conversions, all these advantages confirming compliance of the claimed inventions with the 'industrial applicability' patentability criterion.
This is not the first invention patented by composite author of the Department; during the last two years the team under the supervision of professor VISYASHCHEV patented 5 inventions in the field of electrical power engineering.
According to the head of the Intellectual Property Department Larisa KHMELENKOVA, the Department of Electric Power Stations, Networks and Systems of INRTU Institute of Power Engineering headed by the associate professor Vadim FEDCHISHIN has a high intellectual potential and inventive activity. Starting from 2012 the Department has got 9 patents.
“Nowadays our state pays great attention to the development of Russian market of intellectual property as well as the increase of “inventive activity coefficient”. Our Department is responsible for protection of intellectual property objects created by our University scientists. As of today INRTU is the rightholder of 321 RF patents for inventions and useful models, three certificates for graphic trademark, 133 certificates on state registration of software and databases. The University also makes its first steps towards foreign patenting, - L. KHMELENKOVA says. – The University has two German patents for useful models; now we have got the third foreign patent. It was our first experience of patenting on the territory of the United States. At first we have patented this invention in Russia and only afterwards applied for patents at US and Chinese patent offices”.
