Research On The Ring Network Cabinet Anti-error Locking System Based On The Wireless Ad-hoc Network Technology

Nowadays,distribution networks provide power for hundreds of millions of customers in the large-scale power system,which plays a very important role in the procedure of power generation,transmission and distribution.For the increasingly strict demand of the power quality requirements,the management and operation level of distribution network becomes more and more important.In the distribution network,ring network cabinet has been widely used in the urban distribution network because of its simplicity and reliability.However,when the loop network cabinet is locked or overhauled,it is prone to misoperation,which will affect the operation of the power grid and endanger the personal safety of operators Based on this,this paper designs and develops an anti-error locking system of the ring network cabinet based on the wireless Ad-hoc network technology,which focuses on solving problem of"power on earth knife switch " and " power transmission with grounding equipment in closing position" in the distribution network operation,and effectively prevents the bad events in the operation of the distribution network ring network cabinet.The main research contents of this paper are as follows:First of all,the structure of the system is studied.By comparing the distribution network with the substation system,the procedure of the system is proposed.Then,the technology of wireless Ad-hoc network is investigated.After comparison,the hybrid structure of wireless Ad-hoc networks,which is not limited to the inherent structure is selected.Finally,the wireless Ad-hoc system based on the improved ant colony algorithm is proposed The network structure optimization strategy reduces the communication delay and improves the real-time performance of wireless communication on the premise of ensuring the communication quality.Secondly,in this paper studies the basic principle of the expert system of anti-error blocking is illuminated,and designs the expert system is proposed based on wireless Ad-hoc network technology with clips as the development tool,which realizes the convenience of remote debugging and the accuracy of control;the expert system forms a network structure through the wireless connection of routing nodes,so as to adapt to the changing distribution network structure;the locking logic of ring network cabinet is also designed and the rule base is established to realize the applicability of most devices,the accuracy and readability of rule expression.Finally,the whole scheme of the anti-error locking system of the ring network cabinet based on the wireless Ad-hoc network technology is designed;the anti-error locking system architecture is established,including the station control layers established,the interval layer and the process layer is established,and the anti-error technology is realized at all levels.Field application shows that the design of the ring network cabinet anti-error locking system based on wireless Ad-hoc network solves the problem that the real-time performance of the traditional anti-error locking system cannot be guaranteed.Finally it forms the real-time anti-error information data of the whole power grid equipment,and quickly transmits the locking information.Fundamentally this system solves the occurrence of misoperation accidents,realizes the safe and reliable operation of the equipment,and greatly improves the work efficiency of the staff.
