Method for generating intelligent bus differential protection and corresponding intelligent interval protection in substation

Abstract

The invention discloses a method for generating intelligent bus differential protection and intelligent interval protection in a substation. The method includes: controlling the power-on of the new bus differential protection vertical screen, removing the original bus differential device on the basis of retaining the original bus differential protection screen; placing the bus differential transition interface device at the place where the original bus differential device was removed Configure the bus differential transition interface device; first connect the bus differential transition interface device with the original resetting relay, and then connect with the original circuit breaker protection and the original circuit breaker primary equipment; control interval transformation; when the After the bay transformation is completed, the bay is overlapped with the new bus differential protection. By adopting the technical scheme provided by the invention, it is possible to realize safe transformation from conventional bus differential protection and corresponding compartment protection to intelligent bus differential protection and corresponding intelligent compartment protection.

Description

technical field [0001] The invention relates to the field of electric power technology, in particular to a method for generating intelligent bus differential protection and intelligent interval protection in a substation. Background technique [0002] Electricity is an energy source powered by electrical energy. Electricity was invented in the 1870s. The invention and application of electricity set off the second industrialization upsurge and became one of the three scientific and technological revolutions in the world since the 18th century. Since then, technology has changed people's lives more rapidly. The large-scale power system that appeared in the 20th century is one of the most important achievements in the history of human engineering science. It is a power production and consumption system composed of power generation, power transmission, power transformation, power distribution and power consumption. It is converted into electricity through mechanical energy devi...

Problems solved by technology

Due to the difference in circuit implementation between conventional secondary equipment and intelligent secondary equipment, compatibility problems between conventional secondary equipment and intelligent secondary equipment will occur on the public protection device of bus differential protection

[0004] Therefore, at present, the transformation method for conventional bus differential protection and corresponding compartment protection is only applicable to the transformation of conventional protection, and cannot be applied to the transformation from conventional bus differential protection and corresponding compartment protection to intelligent bus differential protection and corresponding intelligent compartment protection
