specific Embodiment approach 1

[0020] Specific embodiments 1. A power grid dispatching method based on wireless communication,

[0021] Install wireless communication equipment on each power monitoring personnel, and set the transmission radius ra of each communication equipment; each power monitoring personnel is recorded as a node AP;

[0022] Divide all power monitoring personnel into N clusters with radius rb, where rb is greater than ra; N is a positive integer;

[0023] Each cluster includes several node APs, and a node AP only belongs to one cluster, which is recorded as a cluster member;

[0024] A cluster head is jointly recommended by all cluster members in a cluster, and all cluster members can communicate with the cluster head;

[0025] All cluster heads can communicate with the dispatch center;

[0026] The power grid scheduling method based on wireless communication is as follows:

[0027] When a node in a cluster needs to report power monitoring data to the dispatching center, if it is a c...

specific Embodiment approach 2

[0029] Embodiment 2. This embodiment is further limited by Embodiment 1. If a node AP is located within the radius of multiple clusters at the same time, cluster members will randomly join any one of the clusters.

specific Embodiment approach 3

[0030] Specific embodiment three, the further limitation of this specific embodiment and specific embodiment one, if the cluster head of a cluster withdraws from a cluster, then all remaining cluster members of this cluster re-elect a cluster head, and the cluster head of this cluster reports to the scheduling center Report the cluster head update data packet.

Abstract

A power grid dispatching method based on wireless communication relates to power grid dispatching technology. The power grid dispatching method settles a problem of high received communication load in scheduling caused by point-to-point communication in communication with field monitoring personnel in a power grid dispatching process. The power grid dispatching method is based on cluster technology in the communication process. In the electric power dispatching process of the power grid, communication with the field monitoring personnel is transferred to communication between a cluster head and a cluster member through point-to-point communication, so that a dispatching center only performs communication to the cluster head, thereby greatly reducing a communication load in dispatching. The power grid dispatching method is suitable for the electric power dispatching occasion of the power grid.

Description

technical field [0001] The invention relates to power grid dispatching technology. Background technique [0002] Power grid power dispatching is a management method adopted to ensure the safe and stable operation of the power grid, reliable external power supply, and orderly progress of various power production tasks. [0003] The specific work content of power grid dispatching is based on the data information fed back by various information collection equipment, or the information provided by monitoring personnel, combined with the actual operating parameters of the power grid, such as voltage, current, frequency, load, etc., comprehensively considering the development of various production tasks Judging the safety and economic operation status of the power grid, issuing operating instructions by telephone or automatic system, instructing on-site operators or automatic control systems to make adjustments, such as adjusting generator output, adjusting load distribution, swit...
