Problems solved by technology

[0004] The power grid planning in the existing technology only meets the load demand and the balance of power supply and consumption, with more considerations for economy and applicability, and less consideration for safety and reliability. The relevant technical standards are lower than the standards of similar cities at home and abroad. From the source Structural security risks such as "false double circuits" and "coordinated supply" in the power grid have caused hidden dangers of accidents

Embodiment Construction

[0016] The present invention will be further elaborated below by describing a preferred specific embodiment in detail in conjunction with the accompanying drawings.

[0017] like figure 1 As shown, a relay protection configuration device for 110KV substation inter-station communication, including: at least one pair of substations, each of which includes two sections of 10KV busbars; one section of 10KV busbars of one of the substations passes through the inter-substation The tie line is connected to a section of 10KV busbar of another substation, and each of the inter-station tie lines is respectively provided with two inter-station tie circuit breakers.

[0018] The substation includes a backup automatic switching device, and the two sections of the 10KV bus are switched to each other for power supply through the backup automatic switching device.

[0019] Specifically, the number of the substations is 2, which are respectively the first substation 100 and the second substat...

Abstract

The invention discloses a relay protection configuration device for interstation communication between 110 110KV substations. The device comprises at least a pair of substations, and each substation comprises two segments of 10KV buses; and one segment of 10KV bus of one substation is connected with one segment of 10KV bus of the other substation through an interstation communication line. The relay protection configuration device can ensure continuous power supply through the interstation communication line between the two substations in the case of segmented autotomy stop of the substations.

Description

technical field [0001] The invention relates to the technical field of smart grids, in particular to a relay protection configuration device for inter-substation communication of 110KV substations. Background technique [0002] Smart grid is the future development direction of China's power grid. Judging from the fact that the distribution network directly serves users, the construction of an intelligent distribution network ensures uninterrupted and reliable power supply, and can provide users with high-quality power and services, as well as functions such as automatic isolation of distribution network accidents. At the same time, the realization of the self-healing function, which is the main feature of the smart grid, is inseparable from the coordination and cooperation of distribution network planning, relay protection configuration and setting, and distribution network automation. [0003] The distribution network is the part of the power system that directly faces pow...
