Description
Technical field
The utility model relates to the transmission line of electricity monitoring technology, relates in particular to a kind of high altitude mountainous area transmission line of electricity condition monitoring system based on satellite communication.
Background technology
Along with high speed development of national economy, all trades and professions are increasing to the demand of electric power, it is also more and more higher to provide the quality (stability, continuous and follow service) of electric power supply to require to power supply department, and therefore the security of the operation of power networks of ultra-high-tension power transmission line seems particularly important at a distance.
The factor that influences at present the ultra-high-tension power transmission line security of operation mainly contains following aspect:
Artificial outside destroy column foot has a strong impact on transmission line of electricity safety.Along with the rise of metal material, the lawless person steals equipment such as electric power tower tower material, lateral conductor in a large number, causes the transmission line of electricity column foot to collapse in recent years, and transmission of electricity is interrupted, and has had a strong impact on the safety of transmission line of electricity.Abominable ice damage weather has a strong impact on transmission of electricity safety.
The ice damage in the end of the year 2007 allows people re-recognize the harm of icing, and a large amount of icing causes that lead breaks, column foot collapses, and has had a strong impact on the safety of transmission line of electricity.Mountain area high tree growth line ball has a strong impact on transmission line of electricity safety; The mountain area trees can be more and more higher along with growing up, and is pressed onto the lead that passes through the mountain area through regular meeting, causes lead to break or short circuit, had a strong impact on the safety of transmission line of electricity.The circuit of the artificial line walking difficulty in remote mountain areas also is a factor that influences power transmission and transformation line safety; Regular line walking is an important means that guarantees transmission line of electricity safety, yet the unusual difficulty of the artificial line walking of circuit that passes through the remote mountain areas can't determine whether transmission line of electricity exists potential safety hazard, also will have a strong impact on the safety of transmission line of electricity.The ground that digs sandstone, earth excavation destruction column foot around the column foot also is a factor that influences transmission line of electricity safety; The situation of digging sandstone, playing the earthwork is often arranged around the column foot,, also will have a strong impact on the safety of transmission line of electricity in case just might influence the stable of column foot near ground.Influence the safety factor of transmission line of electricity in sum, each supergrid office and Utilities Electric Co. press for and take measures to monitor, take precautions against the various situations generations that influence transmission line of electricity safety.
The transmission line online monitoring system communication technology.
The communication mode that traditional transmission line online monitoring system uses has:
WIFI。This mode is fit to closer distance the environment that can insert Internet.Advantage is to insert simple, zmodem, and the bandwidth height, cost is lower.Shortcoming is that transmission range is short, and power consumption is higher.
Wireless bridge relay transmission.This mode is fit to the environment of moderate distance (1km-100km), and advantage is to insert fairly simple, is convenient to realize and the transmission bandwidth height.Shortcoming is that power consumption is higher, and cost is higher, as long as there is a repeater bridge whole network that lost efficacy influenced, fault-tolerance is low, and transmission range is limited.
GPRS/3G。This mode is fit to long Distance Transmission.It is fairly simple that advantage is to insert realization, distance.Shortcoming is that bandwidth is less, relies on the equipment and the service of telecom operators.
The OPGW(Optical Fiber composite overhead Ground Wire).This scheme is suitable for laying the circuit of OPGW.Advantage is that bandwidth is high, and wired mode reliability is better.Shortcoming is to only limit to lay the circuit of OPGW mode, and when construction difficulty.
More than four kinds of mode mixed transport, as wireless bridge relay+OPGW, wireless bridge+WIFI, WIFI+GPRS/3G or the like.
Former, traditional transmission line online monitoring system is used for general city and small towns mostly, often can obtain more support, such as GPRS/3G, wired ethernet even wifi, commercial power supply also is easier to realize, but for uninhabited, the mountain area that infrastructure lacks, especially be similar to mountain area, plateau etc., can not get the support of any infrastructure probably, for example all multiposition on the transmission line of electricity Qinghai-Tibet Railway do not have wifi, can't connect the internet even not have the signal of mobile operator to cover and commercial power supply, distance is also very remote simultaneously, and in this case, the communication mode of traditional on-line monitoring system just can't use.But often in the such kind of area, because manual inspection is more difficult, the meaning of on-line monitoring is more great, and the demand of this respect is also more strong.
