Embodiment Construction

[0054] The present invention will be further described in detail below, so that those skilled in the art can implement it according to the description.

[0055] It should be understood that terms such as "having", "comprising" and "including" as used herein do not entail the presence or addition of one or more other elements or combinations thereof.

[0056] The power grid itself is a unified system connected by many components. The requirements for the relay protection equipment in the power grid are not limited to correct logic function and reliable operation. Strict cooperation, in the event of an equipment failure, the protection device must move as it should, and cannot be mis-moved. The relay protection setting value is the direct basis for the correct operation of the protection equipment, and the coordination of the action behavior of the relay protection devices at all levels is actually the coordination of the protection setting value. If the correctness of the prot...

Abstract

The invention provides an electromagnetic transient simulation platform-based secondary device modeling method. Based on an existing mature power grid primary device electromagnetic transient simulation (DDRTS) technology, digital models of various relay protection devices in a power grid are built by adopting a graphic simulation support platform system; protection setting values of all levels inthe power grid are input to the digital relay protection device models; and by performing various electromagnetic transient process simulation on the power grid, action conditions of the relay protection devices are observed, so that the correctness of the relay protection setting values of all the levels in the power grid is checked.

Description

technical field [0001] The invention belongs to the field of power systems, and in particular relates to a secondary equipment modeling method based on an electromagnetic transient simulation platform. Background technique [0002] The existing simulation system has the following deficiencies: [0003] Cannot adapt to the trend of continuous upgrading of secondary devices [0004] The protection devices currently configured in the simulation system room are basically the same as the secondary equipment in the actual operation of the substation. However, with the technical update of the protection devices, there will definitely be differences between the devices in the training room and the devices in the actual operation of the substation, and the differences may gradually expand. The purchase of secondary equipment requires a large amount of investment, and the rapid update of equipment requires continuous investment of funds, which brings great troubles to the upgrading a...
