Background
The power system diagram is one of common drawings of the power departments, is mainly used for showing the connection relation between all outgoing line switches in the transformer substation and other transformer substations, and is an important auxiliary tool in power system planning, operation and management, so that a power distribution network manager can clearly and intuitively show the ring network connection condition and ring network distribution proportion of the outgoing line switches in the transformer substation. Such as: the method can clearly and accurately show which circuits are single radiation circuits without looped network in the target transformer substation on the power system diagram drawing, which circuits are inner loop circuits of looped network of the target transformer substation, and which circuits are outer loop circuits of looped network of other transformer substations. According to the distribution condition and proportion of various looped network type lines, distribution network management personnel can immediately determine the feeder line where relevant loads are located in the aspect of power failure analysis, analyze and decide a load transfer plan and a field load control scheme, and clearly display weak links among power supply points of a main distribution network in the aspect of power grid planning and construction, so that the most powerful data support is provided for power grid investment planning, power supply layout, user distribution and the like.
In view of the importance of the system diagram to the safe operation of the power system, various domestic power enterprises, research institutions and scientific universities develop researches on drawing the power system diagram into a diagram. Currently, no precedent for automatically forming the power supply system diagram exists, most power supply enterprises utilize AutoCAD, visio and other tools to manually draw the power supply system diagram, and after drawing is completed, the drawings are printed into a book and then distributed to each application unit for use.
At present, a power supply system diagram is manually drawn by a system, and has certain defects and disadvantages:
(1) Low imaging efficiency and high error rate
Traditional manual drawing is low in drawing efficiency, a large number of drawing staff are needed for manual maintenance, the manpower resource cost is high, manual drawing is easy to make mistakes, and potential safety hazards are brought to line operation and maintenance.
(2) Untimely updating of drawings
The previous drawings are printed after being drawn manually, bound into a book, and distributed to all power departments for use. The phenomenon that drawings are not updated timely is easy to occur when the lines are frequently modified such as overhaul technology modification and the like, so that the safety of production operation is seriously affected.
(3) Inconsistent drawing standard
At present, the power supply system diagrams have differences in the business of all power departments, the aesthetic standard is different, and a unified mapping standard is not formed, so that the types of the drawings are various and disordered, the primitive standard is different, the equipment display is not complete, and the expansion of business requirements can not be well supported.
(4) Integration and application unfavorable for drawing
Because of no unified mapping algorithm and interaction standard, the integration interaction difficulty with other business systems is high, the risk is high, and the large-scale application of drawing data resources in various business fields of power supply enterprises is seriously hindered
With the continuous development of informatization, the traditional manual drawing mode cannot meet the requirements, and a more intelligent and efficient automatic drawing scheme is a future trend.
