Abstract

The invention relates to a detecting and debugging method for a reconstruction and extension project secondary system for an intelligent substation. The detecting and debugging method comprises the steps of configuring an SCD file for a reconstruction and extension substation; establishing a simulation debugging environment for the secondary system of the reconstruction and extension substation; performing pre-debugging on newly-added secondary equipment of the reconstruction and extension substation; and performing onsite linkage test on the newly-added secondary equipment of the reconstruction and extension substation. By adoption of the detecting and debugging method, the debugging process of the reconstruction and extension project secondary system can be optimized; the debugging efficiency is improved; the debugging period of the reconstruction and extension project secondary system can be shortened; the construction cost is lowered; and meanwhile, the onsite debugging workload is effectively reduced while safety risk in debugging is lowered.

Description

technical field [0001] The invention relates to the field of electric power automation, in particular to a detection and debugging method for a secondary system of an intelligent substation reconstruction and expansion project. Background technique [0002] With the development and construction of smart grids in 2009, smart substations have become the mainstream construction model and are being promoted nationwide. Based on the IEC61850 standard, the smart substation transforms the signal connection under the traditional cable connection into a communication connection, which not only simplifies the design of the secondary system of the substation, but also reduces the safety risk during the maintenance of the secondary circuit. The networked transmission of digital signals also brings difficulties to its detection and debugging. The traditional cable secondary circuit is replaced by optical fiber and network, and the AC current, voltage signal and DC control, position and a...
