Abstract

The invention relates to a method and a device for transforming electric analog signals; wherein the method comprises the following steps: transforming the electric analog signals output by a real-time digital simulation device into electric digital signals; processing the electric digital signals to generate standard digital signals meeting communication standards of a transformer substation; processing the standard digital signals meeting the communication standards of the transformer substation to generate sampling value messages meeting the communication standards of the transformer substation; transmitting the sampling value messages meeting the communication standards of the transformer substation to a digital relay protection device to be detected. The electric analog signal transformation device of the invention can be employed to enable the RTDS to detect the digital relay protection device in a convenient and reliable manner.

Description

technical field [0001] The present invention relates to the detection technology of electric power digital relay protection equipment, in particular to the simulation signal conversion device of RTDS-based digital relay protection equipment, and in particular to a power simulation signal conversion method and device. Background technique [0002] In the power system, the relay protection equipment needs to be detected by the detection equipment before it can be integrated into the power grid for operation. The detection equipment used is usually a real-time digital simulation equipment (RTDS: Real Time Digital Simulation). [0003] RTDS can test conventional relay protection equipment that inputs voltage and current through analog interface. However, with the promulgation of the IEC61850 standard, the power industry began to follow this standard to build substations. The input and output interfaces of the required relay protection equipment are Ethernet interfaces or optica...
