A planning method for base station construction of wireless private network in electric power system based on map information

Abstract

The invention discloses a construction planning method of a wireless private network base station in a power system based on map information, which includes calculating or measuring the signal transmission power of all candidate planning base stations; measuring the signal level of 1785-1805MHz and the signal level of 223-235MHz at the terminal position; Calculate the communication coverage of each candidate planned base station; mark it on the map; calculate the best position of the candidate planned base station. The map information-based construction planning method of the electric power system wireless private network base station provided by the present invention researches the LTE230M and LTE1800M signal spectrum and different frequency networking strategy, and proposes the maximum coverage and minimum base station search algorithm based on the measured data at the same time, so as to better The construction adaptability and anti-interference are stronger, the coverage is wider and the power wireless private network that meets the requirements of the power system, and the method of the invention is scientific and reliable.

Description

technical field [0001] The invention specifically relates to a construction planning method for a base station of a wireless private network of a power system based on map information. Background technique [0002] With the development of economy and technology and the improvement of people's living standards, electric energy has become an indispensable secondary energy source in people's production and life, bringing endless convenience to people's production and life. [0003] At present, the development of safe, reliable and efficient smart grid has become an inevitable trend. The smart grid power distribution business has the characteristics of multiple terminal points, wide distribution, large system capacity, and high requirements for real-time performance and reliability. Although the optical fiber communication method has the advantage of strong business transmission capabilities, it is difficult to deploy and construction, and the cost is high, which cannot meet th...

Problems solved by technology

The LTE230 system is a wireless private network communication system working in the 230MHz frequency band. The system relies on the key technology and architecture of LTE, combined with the discrete distribution characteristics of the 230MHz spectrum, and uses carrier aggregation technology to achieve bandwidth transmission. It has the advantages of low cost and wide coverage. Its own bandwidth is small, and the frequency band memory is also interfered by the 230M data transmission station, which limits the service capability of the LTE230 system, and it is difficult to promote its application value alone

The main private network system in the 1800MHz frequency band is the LTE1800 system, which is converted from the standard public network LTE equipment. It has the advantages of large terminal bandwidth, strong support for high-bandwidth services, and an industrial chain. The maintenance cost is high, and it is difficult to support the business of full collection and transmission of the entire smart grid information alone

[0005] Therefore, there is currently no research on the construction planning of wireless private network base stations in power systems, which makes the construction of wireless private network base stations in power systems blank
