Display system and display method for operating characteristics for alternating-current and direct-current power grid based on RTDS (real-time digital system) real-time digital simulation

Abstract

The invention discloses a display system and a display method for operating characteristics for an alternating-current and direct-current power grid based on RTDS (real-time digital system) real-time digital simulation. The display system is equipped with a simulation workbench for establishing an alternating-current and direct-current power grid model, a real-time digital simulator, a protocol conversion card, an interchanger and a power grid characteristic display device; the real-time digital simulator is used for outputting analog amount and digital amount to the power grid characteristic display device through the protocol conversion card and the interchanger; the power grid characteristic display device is used for returning an operation control order to the digital simulator in real time through the interchanger and the protocol conversion card. The display system further comprises a transient data processing unit which is equipped with a transient data extracting unit and a conversion unit; the power grid characteristic display device is equipped with a transient database, a variable database, a searching mapping unit and a replay display device. The display system can be used for realizing visual display of power grid operation characteristics of steady state data, transient data and the like, is reliable in performance, simple and practical.

Description

technical field [0001] The invention relates to the technical field of AC and DC power grids, in particular to an RTDS real-time digital simulation-based AC and DC power grid operation characteristic display system and a display method thereof. Background technique [0002] With the wide application of high-voltage direct current, series compensation, SVC, STATCOM and other high-power power electronic technologies, as well as the gradual promotion of clean energy such as wind power generation and energy storage, the operating characteristics of the power grid have become more complex, and the AC-DC power grid that may appear Accidents will also be more diverse, and the control characteristics of large units, large-capacity HVDC and FACTS devices in the grid are crucial to the recovery of accidents. [0003] The safety and stability of large systems are prominent, and the requirements for the professional quality and operating experience of dispatchers, operation and maint...
