Embodiment Construction

[0038] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0039] figure 1 It is an overall logical architecture diagram of the power distribution terminal control system provided by the present invention. In the present invention, supported by a highly reliable real-time embedded system, the entire control system is installed in the power distribution terminal in an embedded manner, and each module is designed using object-oriented thinking, and the module design is designed in layers based on the principle of strong cohesion and low coupling , data and applications are separated. It not only improves the security of the overall system, but also facilitates version upgrade and function optimization. According to its hierarchical structure, it is divided into hardware platform layer, driver layer, operating system layer, abstraction layer and application layer.

Abstract

The invention discloses a control system used for a power distribution terminal. The system includes a hardware platform layer, a driving layer, an operating system layer, an abstraction layer and an application layer. Unified scheduling is performed by a real-time operating system of the operating system layer. The abstraction layer includes a data engine module, a public service module and a debugging configuration module. The data engine module includes a real-time data sub-module and a historical data sub-module. The real-time data sub-module is used for data real-time storage and analysis of the power distribution terminal. The historical data sub-module is used for recording operation information formed by protection and measurement control function modules and the operation information is used for retrieval of the debugging configuration module. The public service module provides frequently used public interfaces to other modules. The application layer performs measurement control and protection on the power distribution terminal based on the public interfaces, the real-time database sub-module and the historical database sub-module. The control system used for the power distribution terminal performs a hierarchical design in a high cohesion and low coupling principle and data is separated from the application so that the system has the characteristics of being safe, highly efficient and reliable.

Description

technical field [0001] The invention relates to a control system for a power distribution terminal, which belongs to the technical field of power distribution automation. Background technique [0002] Distribution terminal is a general term for various remote monitoring and control units installed on the distribution network site, mainly including feeder terminals, station terminals, distribution transformer terminals, etc. Its functions mainly include: data acquisition, control, data transmission, maintenance, time synchronization, sequence of events recording (SOE), feeder fault diagnosis, single-phase grounding detection, primary reclosing, etc. [0003] As an effective technical means to improve the reliability of power supply, distribution automation has been paid more and more attention by the power sector. The distribution terminal is a necessary equipment for the construction of distribution automation, and its communication network with the main station system of d...
