ДОСЛІДЖЕННЯ РОЗПОДІЛУ МАГНІТНОГО ПОЛЯ ДІЮЧОЇ ДВОКОЛОВОЇ ЛЕП 110 кВ «ЧТЕЦ – ЧЕРНІГІВСЬКА-330» У ЗОНІ ЖИТЛОВОЇ ЗАБУДОВИ ТА МЕТОДІВ ЙОГО ЗМЕНШЕННЯ ДО БЕЗПЕЧНОГО РІВНЯ |
| description |
Purpose. The problem of evaluation and analysis of magnetic flux density of overhead power lines is very relevant now, since the magnetic field of industrial frequency can have a negative effect on human health. The analysis of the magnetic field of the operating double-circuit overhead transmission line was made in this work. This overhead line is in the residential area of Chernihiv, Ukraine. The purpose of this work is to determine safe habitation conditions as a function of the magnetic flux density along the route of two-circuit power line with the voltage 110 kV «ChTPP-Chernihiv-330». Real modes of operation are taken into account. Recommendations are given for reducing the magnetic flux density level in the residential area to a value that will not exceed the standard value. Methodology. Methods of electromagnetic field theory were used to calculate the magnetic field of power lines. The location of the phase wires on different types of supports of the existing power transmission line and the minimum distance between the conductors and the ground were taken into account. The current value of the current in the phases of the transmission line was taken from the Company «Chernihivoblenergo». Also, the calculation of the magnetic flux density was made for the perspective loads of the transmission line. Estimation of the value of the magnetic flux density was made for the zone of one-story and multi-story buildings near power lines. The option of uniform loading of two power transmission lines was considered and the case where the entire load is transferred along one circuit was also considered. Results. In this work, the distribution of magnetic flux density at a height of 1.8 m in the direction perpendicular to the power transmission line for the sections built on supports of the U110-2 and PB110-2 types was obtained. The graphs show that the magnitude of the magnetic flux density at the boundary of the protection zone of the transmission line will be exceed twice the standard value 0.5 μT for the existing and perspective loads. This problem is relevant in the case of transmission lines in single-circuit mode. The graphs of distribution of magnetic flux density on the facade of an apartment building, located at a distance of 20 m from the axis of symmetry of the transmission line, were constructed. As a result, it is shown that at a height of 11 m from the earth's surface, magnetic flux density will be 1.5-2 μT. Practical value. It is determined that safe habitation along the route of two-circuit power line with the voltage 110 kV «ChTPP-Chernihiv-330» can be achieved when facades of an apartment building are removed from the axis of symmetry of the transmission line at a distance of 33 m for high-rise buildings and at a distance of 27 m for one-storey buildings. Recommendations for reducing the magnetic flux density of this power transmission line have been developed. |

За існуючих та перспективних електричних навантаженнях досліджено рівень магнітного поля двоколової повітряної ЛЕП напругою 110 kV «ЧТЕЦ – Чернігівська-330», яка проходить по території одноповерхової та багатоповерхової забудови у м. Чернігів. Показано, що індукція магнітного поля в зоні забудови та на межі охоронної зони може перевищувати безпечний для людини рівень, особливо у випадку роботи ЛЕП у одноколовому режимі. Визначено безпечні умови для проживання населення поблизу даної ЛЕП, зокрема, безпечну відстань від осі траси ЛЕП до місць розташування одноповерхових та багатоповерхових будинків. Показано, що застосування векторної компенсації дозволяє досягти значного зменшення рівня магнітного поля.
