As an important indicator of the electromagnetic environment UHVDC transmission lines, ion flow field needs to be quickly calculated and updated in case meet requirement building a digital twin power system. This paper is based on UFEM starts from two aspects: electric intensity convergence charge density convergence. a) An adaptive iteration factor for update introduced, which can automatically control speed according change degree intensity, ensuring rapid stable density. b) On this basis,...
In order to study the influence of drizzle weather on total electric field ultrahigh-voltage direct current (UHVDC) transmission lines, an ion flow model considering is established. This calculates not only positive and negative ions but also charged tiny water droplets, dust particles, falling raindrops, enabling accurate simulation in weather. Meanwhile, solved by improved upstream finite element method. First, factors mechanism UHVDC lines are studied this article. Then, method used solve...
Most of the existing intelligent parking management systems guide vehicles to park based on available spaces and do not differentiate between vehicle types. However, with increase in number electric vehicles, there is a new need efficiently allocate charging posts those without required For this reason, we an system that can identify type determine whether legal or not. To achieve this, separate stationary from moving lot track are parked accordance area designated by lot. First, use YOLO...
Application of fuel tank status monitoring technology is studied during the operation large and medium-sized vehicles. By means sensor network technology, vehicle on-board terminal periodic data was collected. Vehicle oil sensing historical analyzed processed. Recognition algorithm state in order that each sampling points are identified as 4 states: "Using, filling, leaking, Stopping", to automatically calculate perceive filling time, value, leaking value daily consumption value. To...
As an important part of DC circuit breaker, isolated power supply transformer belongs to AC/DC hybrid equipment. It is necessary adopt appropriate field types in the electric check ensure accuracy results. In this paper, difference between electrostatic and constant analyzed from basic electromagnetic theory. The joint checking method for kind equipment put forward. finite element model 535kV constructed, outsourcing entity used partition. solution completed field. influence air conductivity...
Abstract The accumulation of space charge on the insulation surface can affects distribution total electric field. characteristics dielectrics under negative corona have been studied using spherical plate gaps in this paper. In order to measure potential three insulating materials influence a DC by vibrating electrostatic probe. experiment tested silicone rubber circular specimen and two umbrella-type disks with different curvatures gap. Afterwards, new inversion algorithm was proposed...
When the traditional tower circle method is used to calculate lightning parameters of transmission lines, because radius far greater than span, there will be many overlapping areas. The in overlap areas calculated times, it not only increase calculation amount, but also lead inaccurate results. In this paper, a new statistical for lines proposed. line corridors are divided into block rectangles equal size, which close each other as much possible reduce impact overlap. Taking 500kV Xianmeng I...
