Problems solved by technology
When a distribution network line fails, it mainly relies on manual line inspection to find the fault point. Due to the complex structure of the overhead line, long lines, and poor line inspection conditions, it takes a lot of time to locate the fault.
In the automatic construction of distribution network, if the traditional optical cable channel direct mining method is adopted, the construction and maintenance costs are high, and it is not easy to set up on overhead lines in mountainous areas

The invention relates to an information transmission control system and a method based on an overhead line wireless fault indicator. The system comprises a public network fore-placed computer, a data concentrator and a wireless fault indicator arranged on the overhead line. The wireless fault indicator arranged on the overhead line is connected onto the data concentrator by adopting a wireless cascade mode; the data concentrator is connected with the public network fore-placed computer in a wireless mode; and the public network fore-placed computer is connected with a power distribution network master station via a physical isolation device. the method comprises steps: the wireless fault indicator detects remote signaling displacement and telemetering information in the line and the remote signaling displacement and the telemetering information are uploaded to the public network fore-placed computer; and the public network fore-placed computer is matched with the power distribution network master station for realizing steps of overhead line fault information distribution and real-time telemetering information monitoring. The system and the method of the invention are reasonable, overhead line fault information distribution and real-time telemetering information monitoring function can be realized in a wireless channel transmission mode, and service application needs by the wireless fault indicator can be met.
Description
technical field [0001] The invention belongs to the technical field of power distribution automation, in particular to an information transmission control system and method based on an overhead line wireless fault indicator. Background technique [0002] As the last link of the power transmission and distribution system, the degree of automation of the distribution network is closely related to the quality and reliability of the power supply. evaluation of. At present, in areas where distribution network automation has not been implemented in my country, dispatchers are still blindly adjusting to the circuit diagram. When a distribution network line fails, it mainly relies on manual line inspection to find the fault point. Due to the complex structure of overhead lines, long lines, and poor inspection line conditions, it takes a lot of time to locate the fault. In the automatic construction of distribution network, if the traditional optical cable channel direct mining met...
