Description

Technical Field

[0001] The utility model relates to the technical field of power equipment, in particular to a distribution substation sampling controller. Background Technique

[0002] Modern power systems tend to develop towards large-scale and complex directions. The scale of the power grid is constantly expanding and the operation is more complex. Due to the huge scale of the power grid, complex operation characteristics, limitations of existing control measures, etc., interconnected power grids may affect a wider range and cause great harm when faults occur, which greatly restricts social development. In modern power systems, load frequency control (LFC) will rely on an open communication network for information interaction to achieve frequency stability control of the power system.

[0003] Through patent retrieval, it is found that the publication number: CN202211336351.0 discloses a power system load frequency control method based on sampling control. The steps include: first, establishing a power system load frequency control model, then constructing a Lyapunov functional to establish sufficient conditions for ensuring the stability of power system load frequency control, and finally, based on the stability conditions of the system, obtaining a method for solving the controller. The present invention obtains a method for solving the controller in this way. The obtained controller can allow a larger sampling period change range, has better robustness, can reduce the network transmission pressure, reduce the number of data samplings, reduce the data transmission volume, and reduce the operation cost.

[0004] Existing sampling control devices need to be connected to high-voltage electricity during use. The housing of the sampling control device is made of metal material and has conductivity. When the sampling control device leaks electricity, the surface of the housing of the sampling control device will be charged, which may cause electric shock accidents during operation. To solve the above problems, a distribution substation sampling controller is proposed in this application. Content of the Utility Model

The sampling controller body 1 has a double-shell structure, which can enhance the structural cavity wall of the sampling controller body 1 and improve the anti-damage ability of the sampling controller body 1 during use. The protective outer shell 3 and the protective inner shell 4 are supported by an insulating support base 5. At the same time, an insulating cavity 6 is formed between the protective outer shell 3 and the protective inner shell 4. The protective cover plate 12 and the locking screw rod 15 are both made of engineering plastic and have insulation properties, which can improve the insulation of the sampling controller body 1 during use and enhance the use safety.

[0028] In this embodiment, as Figure 2 and Figure 3 shown, heat dissipation openings 7 are provided on both end surfaces of the sampling controller body 1. The heat dissipation openings 7 respectively penetrate through the cavity walls of the protective outer shell 3 and the protective inner shell 4.
