An Electric Quantity Merging Unit Used in Dynamic Simulation System

Abstract

The invention provides an electrical quantity merging unit used for a dynamic simulation system. The electrical quantity merging unit used for the dynamic simulation system comprises a data collecting module, a data processing module and a data outputting module. The data collecting module comprises an A / D conversion module, a filtering module, an integration module, a sampling module and a synchronization module, wherein the A / D conversion module, the filtering module, the integration module, the sampling module and the synchronization module are sequentially connected. The A / D conversion module is connected with an electromagnetic transformer through 12 analog quantity input interfaces. The data outputting module comprises 12 optical fiber output interfaces and after framing and coding are conducted on double-route digital signals output by the data processing module, the double-route digital signals are sent to a digital protection device through the same optical fiber output interface. Compared with the prior art, the electrical quantity merging unit used for the dynamic simulation system solves the problem of performance detection under the condition that abnormity occurs when an intelligent transformer relay protection device in the dynamic simulation system outputs data in a merging unit.
