DETERMINATION OF ANALYTICAL CALCULATION ERROR OF MAGNETIC FIELD OF HIGH-VOLTAGE CABLE LINES WITH TWO-POINT BONDED CABLE SHIELDS CAUSED BY NON-UNIFORM CURRENT DISTRIBUTION IN THE SHIELDS
This paper deals with the determination of analytical calculation error of magnetic field of high-voltage cable lines in two-point bonded cable shields caused by non-uniformity of the current distribution in the shields. The relative error is determined by comparing numerical calculation of magnetic...

В работе определена относительная погрешность аналитического расчета индукции магнитного поля трехфазной кабельной линии; обусловленная неравномерностью плотности тока в экранах одножильных кабелей. Погрешность получена путем сравнения численного расчета в программной среде COMSOL Multiphysics с аналитическим методом расчета. Показано; что максимальное значение погрешности не превышает 8 %. Полученные значения погрешности верифицированы путем тестирования численного расчета и подтверждены результатами эксперимента. Обоснована корректность аналитического расчета магнитного поля кабельных линий в точках его нормирования при двухстороннем замыкании экранов кабелей; выполняемого без учета неравномерности плотности тока в экранах кабелей.
