Volkhonskyy A. Operative definition of active power corona losses in high-voltage electric transmission lines

The object of research: high-voltage lines of an alternating-current (HVL). The purpose of research: development both research of a technique and algorithm of operating definition of corona losses in HVL. Methods of a research: methods of a mathematical statistician, numerical methods of optimization, methods of a design of experiments and statistical trials. Theoretical and practical results and innovations: improved technique of operating definition corona losses with usage of modern loggers of the information; first time are developed the algorithms of operating identification of passive parameters of equivalent circuits of a direct sequence HVL are researched; first time is shown, that the operating definition of passive parameters of equivalent circuits of a direct sequence of HVL allows to specify parameters of its mathematical model and to increase an exactitude of definition corona losses; technique of operating definition of dependencies of corona losses from voltage for the first time is offered. A subject and degree of application: the algorithms and programs of operating determination of corona losses are introduced in a south-west electric power system of Ukraine. Effectiveness of implantation: a heightening of an exactitude of optimization of flowing conditions of electropower systems. Sphere of application: electrical networks 330 kV and higher.
