Problems solved by technology
The traditional centralized architecture communication service needs to maintain a large number of connections and data caches, which brings a large load and time and space overhead to the intelligent management unit (time and space overhead, referring to memory space and time consumption), which is very difficult for local protection devices and The interoperability between intelligent management units has a greater impact

Embodiment Construction
[0042] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0043] Such as figure 1 Shown is a schematic diagram of the system structure of the intelligent management unit. The communication service of the intelligent management unit adopts a distributed service architecture. By configuring the balance factor, the general control program combines the pre-configured balance factor to automatically determine how many communication services to start, which communication services are connected to which local protection devices, etc., and all connected The in-situ protection device automatically connects to different distributed services according to the preset balancing factor, realizing the load balancing effect of the intelligent management unit. For the newly added in-situ protection device, the newly added in-situ protection device can be imported through the incremental guide mode, and the access process of t...

The invention relates to a method for realizing self-adaptive load balancing by multi-channel connection of an intelligent management unit. The model of an in-situ protection device is imported into the system, and the balance factor N=0; the adaptive load-balance mode is initialized; an unconnected in-situ For protection devices, the master control program starts a new communication service; obtains the remote signaling and telemetry points of the device, and sums the remote signaling and telemetry points of the current communication service management; the master control program judges the total telemetry and telemetry points of the current communication service management Whether the number of signal points exceeds the threshold; the current communication service is connected to the local protection device, and the number of remote signaling and telemetry points managed by the current communication service is updated; the operation of all communication services is monitored until the end. The invention realizes the load balancing of the in-situ protection intelligent management unit, the device can be upgraded independently, the configuration is simple without manual intervention, and the single point failure risk of the communication service adopting the centralized structure is avoided.
Description
technical field [0001] The invention belongs to the technical field of in-situ protection of electric power systems, and in particular relates to a method for multi-channel connection of an intelligent management unit to realize self-adaptive load balancing. Background technique [0002] In-situ protection technology is a new technology in the field of relay protection proposed by the State Grid Corporation of China in recent years. In-situ protection devices and intelligent management units are the latest applications of this technology in the field of relay protection. The in-situ protection device is installed close to the primary equipment, without protection, affected by external factors such as meteorological environment, geographical location, electromagnetic field, etc., and has no LCD panel. The State Grid Corporation of China proposed to use the intelligent management unit to centralize and intelligently manage the in-situ protection devices of the whole station. ...
