Description
Technical field
The utility model relates to the distribution network systems of the automatic monitoring management of a kind of intelligence supply line.
Background technology
Along with deepening continuously of high speed development of national economy and reform and opening-up, power consumer is also more and more higher to the requirement of the quality of power supply and power supply reliability.Because current grid equipment is mainly electric line, the control switch equipment of various electric pressures, the management and the operation of measuring equipment, the artificial on-the-spot local operation of main dependence, need the special messenger to remove to copy the power consumption that to determine this unit behind the ammeter with electric unit with the power consumption of electric unit, it is bigger to consume manpower and financial resources, and is easy to generate deviation and error.
In addition, the distribution line that power supply department need be drawn this area moves towards figure, represents a lot of various signs in the drawings, and these promptly can not show actual geographical position, load and the fault that can not intuitively observe, monitor the electrical network actual motion.The reason great majority of fault need artificial field observation to determine, cause the fault feedback speed slow; Route protection generally all adopts fuse and the disappearing realizations such as controller of shoving, and needs on-the-spot the setting to adjust, the setting value set position, and waste of manpower is under the efficient; Power supply department is difficult to understand field data, and management makes a mistake easily.Because the electrical network long-term work is under natural environment, bear vibration, drench with rain, sunshine, harmful effect such as expand with heat and contract with cold, cause the loosening and loose contact of joint etc. easily, cause ageing equipment, cremate to such an extent as to cause electricity, burn out dropping of equipment, tripping operation, voltage ripple of power network and power failure and electric line, even cause fire and life safety, bring tremendous loss to economy, brought huge obstruction to social development.
Continuous development along with urban distribution network, contact and segmentation in the middle of the 10kV distribution line are on the increase, circuit becomes increasingly complex, what install on the 10KV circuit is that setting current is 600A, 400A, the switch of 200A, load is all heavier at ordinary times, when overload appears in circuit, transient fault, any situation such as permanent fault, switch all can automatic trip, at present on the circuit without any watch-dog, so when the tripping operation outage occurring, power supply department often and be difficult to perceive immediately proposes new requirement for scheduling and repairing personnel, actual operating that promptly must power distribution network fully aware of, otherwise can cause the line outage time that enlarges, increase fault track walker workload, more likely the mistuning degree can take place, misoperation gently then causes the distribution accident, and is heavy then human casualty accident takes place.
In recent years, numerous electric companies distribution automation system that put into operation generally is at distribution transformer, on-pole switch, and switching station is installed relevant terminal, communication channel mostly is the optical fiber mode, it is huge that main station system is built, and comprises traditional SCADA, GIS, advanced applied software etc., causes the distribution automation system investment big, system builds complicated, utilance is low, and degree of being practical is not high, has caused the system product of poor efficiency with high investment.
Summary of the invention
