Problems solved by technology

[0002] At present, in the 10kV distribution network, the distribution network is becoming increasingly complex and the structure of the distribution network is frequently adjusted, which brings the following inconveniences to the distribution network dispatching management. First, due to the continuous development of the urban and rural distribution network, the structure of the distribution network changes frequently, static The distribution network simulation diagram board cannot be changed in a timely and effective manner, and often does not match the actual situation on site
At the same time, due to the limited function, the daily maintenance of the simulation board is more complicated. At the same time, the simulation board cannot fully and accurately reflect the internal wiring mode and interconnection relationship of the distribution network equipment, and the dispatcher cannot intuitively understand and grasp the operation mode of the distribution network. , so it is not conducive to the rapid release of dispatching orders and the emergency treatment of abnormal accidents; moreover, with the increasing number of distribution network closure and power regulation work, the switching operations of switches on the distribution network column and ring network cabinets are more frequent, and in actual operation Among them, the operators fill in the operation tickets manually without performing simulated operations, and there may be irregularities in filling in the operation tickets. There are no effective prevention and control measures for the illegal operations of the operators, and there is a lack of effective closed-loop management.
In addition, according to the "Regulations on Electric Power Supervision", the urban power outage notice must be specific to the requirements of the community. In the release of daily power outage information, there is a problem that the customer service center personnel cannot obtain power outage customer information in the first time through effective information channels.

Embodiment 1

[0014] Embodiment 1, the power distribution decision-making function of power distribution network closure

[0015] When the 10kV distribution network is closed and looped, the dispatcher can call out the load, voltage and current at both ends of the closed loop line from the system in time, as well as the status of the ring main unit, the switch on the pole, and the fuse on the closed loop line. Security dispatch provides on-site real-time data. exist figure 2 In the middle, take Shengao substation 10kV Xiazhu line 115 and Guanzhuang substation 10kV Guanzhuang line 228 connection switch as an example, the load, voltage and current data of the two closed-loop lines are all taken from the real-time data of the dispatching automation ON2000WEB system, and the closed-loop line The state of the ring network cabinet, the switch on the column, and the fuse are simulated and displayed by manual setting, which is consistent with the on-site state. If the state of the on-site switch ...
