Description

TECHNICAL FIELD

[0002] With the promotion of intelligent charging business of power enterprises, fee control and load control technology is gradually intelligentized and popularized, and the technology is mature. In order to protect people's livelihood, the state has introduced policies such as orderly power utilization, and needs to implement multi-round control on the load of large power users. However, the existing fee control and load control technology cannot well solve the problem of multi-point switch control.

[0003] The fee control device is installed at the metering point. When the power consumption of the power user reaches the arrears threshold, the remote system issues a trip command through the collection terminal, and the fee control controller completes the remote power-off control. If the fee control is only implemented at the metering point for relatively large power users, the remote fee control will cause the entire back-end of the metering point to be powered off after the user is in arrears, which has a large impact and is not selective, and the control is not flexible enough. If multi-point switch round control is to be implemented, the control points are not at the same location, so it is necessary to increase the collection terminal at each control point, issue a trip command through the collection terminal, and then complete the switch control through the fee control controller.

[0038] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0039] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0040] In this embodiment, as Figures 1-4 As shown, the first terminal 1 can not only implement local fee control, but also parse the received round-by-round control commands from the acquisition terminal, and send multiple round-by-round control commands to the second terminal 2 via wireless remote transmission technology. The second terminal 2's corresponding second composite controller 205 completes the switch tripping and closing tasks, realizing multi-round wireless remote control. For small-load dedicated transformer users implementing metering point fee and load control: For new users, a fee and load control metering device including the first composite controller 105 can be directly installed; for existing users, the first terminal 1 is installed at the metering point, and the second terminal 2 is added on the controllable side to implement fee and load control for the user's switches.

This is also applicable to ground-mounted metering installations. Figure 3 As shown, the metering point is outdoors, using a high-voltage power supply and metering system, installed as a pole-mounted unit.

For heavy load users, the effectiveness of the fee control and the negative control can be ensured, and the power department can help to manage the fee control and negative control users in a large scale and efficiently.

[0043] As shown, Figure 10 、 Figure 11 The first line break monitoring 1052 can monitor the effectiveness of the fee control and negative control of the user in real time, and store the state information of whether the user load switch is controllable in the third CPU processor 10521, and upload to the remote system through the 485 interface of the special variable acquisition terminal 6. The round control expansion 1055 and the round identification 1056 receive and analyze the extended round control command of the special variable acquisition terminal 6, and can also receive the control commands of round one and round two of the special variable acquisition terminal 6. The third CPU processor 1052 of the first line break monitoring 1052 adopts an STC15F chip, can remotely transmit the round control command analyzed by the first CPU processor 1053 to the second terminal 2, and can also receive the line break monitoring information and the switch state information of the second terminal 2, and upload to the remote system through the 485 interface of the online monitoring first CPU processor 1053.
