The Study Of Distributed Digital Bus Protection Based On Directional Discrimination

In various types of protection, as the special role of bus, the bus makes the protection become very important. This paper details the busbar protection equipment development process, making the busbar protection of a comprehensive understanding, with the new technology, the development of new devices and applications, the realization of busbar protection methods have also changed, making Distributed busbar protection busbar protection has become more reliable, simpler method.Distributed busbar protection busbar protection research at this stage is a major issue in this paper based on the combination of protection direction Distributed busbar protection theoretical knowledge in the use of the relay protection equipment SEL company under the premise of using its distribution in the interval protective equipment provided by the protection function, through the use of the company's proprietary SEL MIRRORED BITS^? communications, coupled with SEL-2100 logic processing unit can be achieved bus Distributed protection. Distributed busbar protection of handling large amounts of data scattered to the interval protection device to speed up the real-time data processing, communications data transmission only of the state, greatly reducing the volume of communications data, while also lowering the logical processing unit load and achieve a distribution fast bus protection.Distributed busbar protection to meet the protection of the power industry under the requirements of busbar protection no longer makes a loop by the restrictions, and save a lot of cables, making investment costs much lower. After the practical application of the scene shows that the realization of the program of simple, stable and reliable operation.
