Description

Realize distribution automation QoS of survice support method
Technical field
The present invention relates to wireless communication field more particularly to a kind of realization distribution automation QoS of survice support methods.
Background technology
With the continuous improvement of Social Informatization Level, build characterized by " informationization automates, interactive ", covering The intelligent grid system of the links such as power generation, transmission of electricity, power transformation, distribution, electricity consumption, scheduling has become the inexorable trend of future development.Electricity Integrated new trend and the direction for running and becoming power network development is netted, traditional dispatching of power netwoks needs to adjust towards realization with distribution Degree, monitoring, integrated, intensive, lean the target transition of operation.The distribution communication technology is then distribution automation management system One of key technology.
Intelligent power distribution Network Communication mainly have at present light communication, carrier wave power line for communication and public network wireless broadband communication this Three kinds of communication modes.First, for optical fiber telecommunications system because reliability is high and it is insensitive to electromagnetic interference, capacity is big, is suitble to In the communication as 110kV/35kV substations to 10kV power distribution rooms/switch room, and for the not high 10kv of required communication rate And following low and medium voltage distribution network, then since optical fiber is expensive and is not easy to multiplexing and multiple connection, then should not use.Secondly, power line carries For wave communication due to quick construction, cost is relatively low, substantially without maintenance, is relatively more suitable for the specific feelings of China's upgrading urban and rural power grids Condition, but the rate of its transmission, reliability and the ability in power supply interrupted district normal work still have larger dispute at present.In addition, with The continuous improvement of power technology development level, have in intelligent grid differentiated service quality (Qual ity of Service, QoS) the power distribution automation business (such as power distribution automation business, metering automation business, video monitoring service) of demand is continuous It is universal so that traditional power line carrier can not adapt to such business demand very well.Finally, public network wireless broadband communication is disobeyed Rely in electricity grid network framework, wide coverage, while have many advantages, such as with roomy, long transmission distance, non line of sight transmission.Exist at present Southern Power Grid Company, low-voltage collecting meter reading business generally use public network wireless broadband communication technology.But existing public network WiMAX skill Art can not all provide specific aim guarantee for power industry.It is specific as follows:
(1) it is lack of pertinence.Existing public network WiMAX QoS security mechanisms are had no for the special of power distribution automation business Consider.Since power system service is not the core business of public network operator and priority support object, at present, as shown in Table 1, Mainly from real-time index (time delay), reliability refers to the QoS security systems of third generation partner program tissue (3GPP) specification It marks (packet loss) and three angles of data rate index (bearer types) considers the QoS of business.And " 12th Five-Year Plan " is matched at this stage Automation business similarly has specific demand in addition to weighing above three index for safety and channel connected ratio. In addition, specific distribution automation business is different to the weighting degree business of the investigation of each QoS index, and 3GPP rule at present The QoS security systems of model regard to each QoS index as equal.Therefore, the QoS security systems of 3GPP specifications have no and do not have at present Specific aim.
Table one
(2) lack scalability.First stage " 12th Five-Year Plan " distribution automation business mainly includes power distribution automation, metering certainly Dynamicization business and a small amount of video monitor business.And follow-up distribution automation business will also include distribution line pilot protection, big model The business such as business, monitoring of equipment in the video monitoring that encloses, user room.These business are each to have respective QoS demand by oneself, regards on a large scale The input of frequency monitoring business subsequently needs to increase the investigation of the QoS indexes such as delay variation.But the QoS of 3GPP specifications is protected at present Barrier system is had no without scalability.
To sum up, from construction cost, difficulty of construction, construction period, communication support, QoS guarantees, safety, easy care Property etc. integration requirements consider, traditional optical fiber and carrier wave power line transmission be not well positioned to meet 10kv and following mesolow The requirement of power distribution network development.And consider from specific aim, scalability angle, existing public network wireless broadband communication also can not be electricity Lixing industry provides complete QoS security systems.
