Problems solved by technology

In recent years, with the continuous advancement of UHV AC and DC projects, a large number of relay protection devices using new principles and new technologies, new DC control and FACTS devices have emerged in the power grid, making the safety and stability control of the system very complicated.
[0003] With the promotion and application of digital substation protection technology, it is difficult to verify the function of the protection device by using the traditional static test method. The RTDS-based simulation modeling analysis method has a relative advantage in the electromagnetic transient stability of the power grid.

Abstract

The invention provides a moving die simulation test system and method for an intelligent substation protection device, and relates to a model system capable of being effectively applied to power system real-time simulation analysis. A simulation model is built through an RTDS. The intelligent substation protection device and related secondary devices (a network switch and a merging unit) of the intelligent substation protection device are connected. A closed-loop simulation test is conducted on the intelligent substation protection device. Motion and behaviors under various situations of the protection device are observed, and thus the functions of the protection device are examined.

Description

technical field [0001] The invention relates to an intelligent substation protection device dynamic simulation test system and method, which belongs to the technical field of RTDS-based 66kV intelligent substation protection device dynamic simulation system, and can be effectively applied to the construction of a power system real-time simulation test system. Background technique [0002] For a long time, people have done a lot of research on the simulation of the power primary system, but there is relatively little research work on the simulation of the secondary system such as protection. In recent years, with the continuous advancement of UHV AC and DC projects, a large number of relay protection devices using new principles and technologies, new DC control and FACTS devices have emerged in the power grid, making the safety and stability control of the system very complicated. [0003] With the popularization and application of digital substation protection technology, it...
