Abstract
In this paper, based on the design of the power system protection of computer integrated automatic reclosing, including integrated reclosing the principle of integrated reclosing the composition, reclosing relay and the co-ordination, installation of hardware and software design part of the design. And details on the single-phase automatic reclosing, the three-phase automatic reclosing, integrated automatic reclosing, and the basis for selection of a 110 KV line to automatically switch on Computer Integrated Design Reclosing installations reclosing and the election of the two functions, can work in the "single-phase automatic reclosing," "three-phase automatic reclosing", "Comprehensive automatically switch on" and "disabled" in four ways. Trip after the single-phase, single-phase reclosing not check the same period, in the three-phase reclosing under way, check the same period, non-pressure check and not check the same period, and so logical. Reclosing of "accelerated after the" manner and relay meet. Computer Integrated Computer automatically reclosing relay device is an important component of the automatic reclosing relay between closely with the good cooperation can be more quickly removed most cases the failure to improve power supply reliability, the system Safe and stable operation to have an extremely important role.
