Description

Technical Field

[0001] The present invention relates to the technical field of anti-interference of distribution networks, and in particular to an anti-interference interface connection structure for transmitting high-frequency signals and a method thereof. Background Art

[0002] The self-healing control of smart distribution networks means that the smart grid system can detect its own operating status. If there is a problem with its own operation, the distribution network system can restore the problematic state to the pre-set normal state in some way without sending relevant technical personnel for maintenance. This saves human resources and reduces the danger for staff during maintenance. The self-healing control of smart distribution networks mainly includes four processes, namely information collection, diagnosis, decision-making and execution. This process conducts real-time evaluation of the operating status of the entire distribution network. If there is a problem with the power grid status, the system can quickly handle it to ensure safe power operation and prevent accidents.

[0003] The existing acquisition process is based on the beat frequency generation mechanism and principle. The injection position, time, phase, amplitude, phase, frequency and other parameters of the high-frequency signals injected twice will cause errors in the synthesized beat frequency signal, thus affecting subsequent fault identification.

[0018] Step 4: After the secondary copper conductor is adjusted, the high-frequency signal information received will be partitioned and strengthened in terms of phase, amplitude, phase and frequency, and then integrated with the signal at the main end interface to complete the compensation output of a single high-frequency signal.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. In the present invention, the interface needs to be connected to the equipment used in the power distribution network system. Each group of interfaces adopts a dual-interface design, which are a main-end interface and a secondary-end interface. The main-end interface is connected to the main line of signal acquisition, and the secondary-end interface is also connected to another group of signal acquisition lines on the same path. When collecting signals, the main-end interface collects one or two high-frequency signals, and the secondary-end interface also collects high-frequency signals twice during the process. After receiving the two signals, the processing module synthesizes the parameters such as the injection position, time, phase difference, amplitude, phase, frequency, etc., and finally forms a beat frequency signal;

[0021] 2. In the present invention, the first main-end copper conductor and the second main-end copper conductor are distributed on the upper and lower sides of the main-end line board. The two groups of main-end copper conductors can realize dual-path transmission and collection of high-frequency signals, and the first secondary-end copper conductor, the second secondary-end copper conductor and the third secondary-end copper conductor constituting the secondary-end contact perform secondary compensation collection after each signal collection by the main-end copper conductor. The transmission rate of the three groups of secondary-end copper conductors is lower than that of the main-end copper conductor, but the information of the high-frequency signal can be transmitted in partitions. Each independent secondary-end copper conductor is responsible for the specified high-frequency information. After each high-frequency signal transmission, the three groups of secondary-end copper conductors inside the secondary-end interface can be adjusted according to the signal analysis at the main-end interface. The high-frequency signal information received by the secondary-end copper conductor after adjustment will be partitioned and strengthened in terms of phase, amplitude, phase and frequency, and then integrated with the signal at the main-end interface to complete the compensation output of a single high-frequency signal.

[0022] 3. In the present invention, the primary guide rod and the secondary guide rod can respectively control the corresponding double-end contact brush to rotate. When the main-end interface collects the high-frequency signal, the processing module will analyze it and compare the collected high-frequency signal with the preset high-frequency signal information, so as to analyze the data information missing from the current signal under interference.

The secondary-end interface is used to enhance the signal source of this part, and then it is integrated with the high-frequency signal at the main-end interface to complete the anti-interference compensation operation.

Each group of interfaces adopts a dual-interface design, namely a primary-end interface (3) and a secondary-end interface (4). The primary-end interface (3) is connected to the main line of signal collection, and the secondary-end interface (4) is also connected to another group of signal collection lines on the same path. Step 2: When collecting signals, the main end interface (3) collects one or two high-frequency signals, and the secondary end interface (4) also collects two high-frequency signals during the process. After receiving the two signals, the processing module synthesizes the injection position, time, phase difference, amplitude, phase, and frequency parameters to finally form a beat frequency signal; Step 3: The first main-end copper conductor (1011) and the second main-end copper conductor (1012) inside the main-end interface (3) can transmit signals. After each high-frequency signal transmission, the three groups of secondary-end copper conductors inside the secondary-end interface (4) can be adjusted according to the signal analysis at the main-end interface (3); Step 4: After the secondary copper conductor is adjusted, the received high-frequency signal information will be partitioned and strengthened in terms of phase, amplitude, phase and frequency, and then integrated with the signal at the main end interface (3) to complete the compensation output of a single high-frequency signal.
