The term "and/or" refers to and includes any and all possible combinations of one or more of the associated listed items.
In a first aspect:
referring to fig. 1, an embodiment of the present invention provides a method for identifying a hierarchical relationship of feeder lines in a low-voltage distribution area, including:
s10, acquiring a first pulse signal of each feeder line through a reading device, and sending the first pulse signal to a branch box;
s20, acquiring a second pulse signal of each branch box through the reading device, and sending the second pulse signals to branch points;
s30, acquiring a third pulse signal of each branch point through the reading device, and sending the third pulse signal to the intelligent distribution terminal;
and S40, identifying the third pulse signal according to the intelligent distribution and transformation terminal to obtain the hierarchical relationship of the feeder line of the low-voltage distribution area.
It should be noted that identification of the feeder hierarchy relationship of the low-voltage distribution area is crucial to the evaluation of the operation state of the power line. The principle basis of the power line operation state evaluation is mainly to analyze and judge the historical and current operation conditions of the power line, and therefore fault defects and hidden dangers of operation at a certain time in the future are predicted and eliminated in time. However, the actual operation situation of the low-voltage distribution network in the current intelligent distribution area cannot be mastered in real time, and the reason is as follows: the graphs of low-voltage power supply lines of an intelligent transformer area, a low-voltage line state evaluation model, state evaluation measurement data and the like are not brought into a power distribution network management system, unified monitoring is not realized like a medium-high voltage power distribution network, a power utilization information acquisition system of the low-voltage power distribution network only realizes real-time or quasi-real-time acquisition of user ammeter data at present, a marketing system only realizes the dependency relationship between a low-voltage distribution transformer and a user side ammeter, and unified scheduling monitoring is not carried out on the graphs of the low-voltage power supply lines and the low-voltage line state evaluation model. Secondly, a large number of distributed power supplies are connected into a low-voltage power supply network through an intelligent electric meter, and the running state of the low-voltage power distribution network needs to be effectively evaluated in order to achieve the goal of optimizing the consumption of clean energy. The primary task of the operation state evaluation of the low-voltage distribution network is to identify the hierarchical relationship of the feeder lines of the low-voltage distribution area, namely, the hierarchical analysis of the feeder lines of the low-voltage distribution area of a typical intelligent distribution area. Therefore, the present embodiment aims to provide a method for identifying a hierarchical relationship of feeder lines in a low-voltage distribution area.
It should be emphasized that, the total number of user nodes in the power grid on a certain phase in the smart platform area is n, and the total number of user nodes in the power grid is influenced by the communication distance and even by other factors such as noise interference during the communication process, so the number of user nodes that the gateway can directly and reliably communicate is necessarily smaller than the total number of user nodes in the power grid, and the number of user nodes that the gateway can directly and reliably communicate is m, so that (n-m) user nodes in the smart platform area are physically connected but disconnected on the data link layer. In order to establish the power line carrier communication network of the whole low-voltage distribution network, data links from gateways of all phases to partial user nodes in the power line communication network should be established, and then the user nodes are taken as routing nodes, so that the communication distance is expanded, and all the data nodes can be accessed into the low-voltage power line communication network.
Specifically, fig. 2 is a schematic diagram of identification of a feeder hierarchy relationship in a low-voltage distribution area according to this embodiment. Fig. 3 is a flow chart of identification of feeder hierarchy relationship in a low-voltage distribution area. The intelligent distribution terminal considers that the hierarchical structure of the topology is B1111- > K111- > D11- > intelligent distribution terminal. The hierarchical relationship of the low-voltage feeder lines can be identified by the identification means described in fig. 3. And when a plurality of data lines upload data, a topological structure is formed.
As shown in FIG. 2, in the low-voltage power line communication network, devices which can receive pulse characteristic signals are arranged at B1111, K111 and D11 and an intelligent distribution terminal, and the feeder level of the low-voltage transformer area is identified through the pulse characteristic signals received by the intelligent distribution terminal. The method provided by the embodiment is described as follows by taking one branch point as an example, wherein the branch points are collected at the intelligent distribution terminal:
first, B1111 is a line hierarchy where the user feeder is located, and is directly connected to the consumer at the user end, and the upstream line is a branch box line. In step S10, a reading device is installed on each subscriber feeder line (L11, L12, L13), and then a first pulse signal of each subscriber line is acquired by the reading device, and is sent to a branch box, and the branch box collects the first pulse signal to generate a second pulse signal.
Further, the branch box is located on the line level K111, that is, the upstream line of B1111. A reading device is provided on each branch box, and then in step S20, a second pulse signal of each branch box is acquired by the reading device, the second pulse signals respectively flow through the lines L1, L2 and L3, are finally collected to the position of the branch point, and are processed by the branch point to generate a third pulse signal.
Further, the branch point is located at a line level D11, i.e. the upstream line of K111. A reading device is arranged at each branch point, and then in step S30, the reading device acquires the third pulse signal of each branch point, and sends the third pulse signal to the intelligent distribution terminal for aggregation.
Finally, in step S40, the summarized third pulse signal is identified according to the intelligent distribution terminal, so as to obtain the hierarchical relationship of the feeder line in the low-voltage distribution area.
In one embodiment, the identification logic principle of the low-voltage distribution area feeder hierarchy identification technology is that when the intelligent distribution terminal is communicated with a low-voltage fault sensor installed at D11, the intelligent distribution terminal is required to send out a pulse current signal. The low-voltage fault sensor installed at the K111 position and the low-voltage monitoring unit of the meter box installed at the B1111 position can detect pulse current signals and inform the intelligent distribution and transformation terminal, and the intelligent distribution and transformation terminal can judge that D11 is an upper node of the K111 and the B1111.
In one embodiment, the identification process of the low-voltage distribution area feeder hierarchy relation identification technology is that the intelligent distribution terminal sequentially notifies each low-voltage intelligent device to generate a pulse current signal. When the low-voltage fault sensor installed on the K111 sends out a pulse current signal, the low-voltage monitoring unit of the meter box installed at the position B1111 can detect the pulse current signal and inform the intelligent distribution transformer terminal. The intelligent distribution terminal can judge the upper nodes of K111 and B1111. When installing table case low pressure monitoring unit at B1111 and sending the pulse current signal, no low pressure smart machine can receive the pulse current signal, and the intelligent distribution terminal has been judged that B1111 is end equipment.
In one embodiment, the first pulse signal, the second pulse signal and the third pulse signal are all rectangular wave signals.
The pulse signal is a discrete signal, has various shapes, and has a certain periodicity, while the waveforms are discontinuous on the time axis (there is a significant interval between the waveforms) compared with a common analog signal (such as a sine wave). The rectangular wave signal passes through a 74LS74D trigger of an external circuit, a monostable trigger and an amplifying circuit, and is designed to realize a low-frequency pulse signal generator, wherein the frequency of the low-frequency pulse signal generator is 1-999Hz, the manual duty ratio is adjustable, and the amplitude is 3.6V-27V.
According to the method for identifying the hierarchical relationship of the feeder line of the low-voltage distribution room, the reading devices are installed on different levels of the feeder line of the low-voltage distribution room of the intelligent distribution room to identify the pulse characteristic signal sent by the terminal device, so that the hierarchical relationship of the feeder line of the low-voltage distribution room of the intelligent distribution room is quickly identified, and the method has the advantages of being low in cost, high in identification speed and high in result accuracy.
