Abstract

The invention discloses a flexible direct current conversion protection link test system, which comprises a real-time simulation system and a tested system, wherein the real-time simulation subsystem comprises a real-time simulator and a power module characteristic simulation device; the tested system comprises a power unit control protection device and a converter valve control protection device. The analog quantity output end of the power module characteristic simulation device is connected with the analog quantity input end of the power unit control protection device; the digital quantity input end of the power module characteristic simulation device is connected with the digital quantity output end of the power unit control protection device. According to the flexible direct current conversion protection link test system provided by the invention, the protection link test is carried out through the actual power unit control protection device, and a traditional software simulation test is replaced, so that a more real and complete test is realized; the technical problem that an existing flexible direct current conversion protection link test system is low in test accuracy is solved.

Description

technical field [0001] The present application relates to the technical field of flexible direct current, in particular to a flexible direct current commutation protection link test system. Background technique [0002] The functional test and dynamic performance test (Functional Performance Test / Dynamic Performance Test, referred to as FPT / DPT) of the flexible DC control and protection system is an important link between the design, manufacture, control and protection strategy in-plant verification of the control and protection system, and engineering site commissioning and operation. It is also an important means to test and ensure that the control and protection system is fully functional, stable and reliable. [0003] Existing FPT / DPT tests are generally based on real-time simulation systems. The real-time simulator is used to simulate the operating state of the flexible DC primary equipment, and is connected to the control and protection equipment through a high-speed ...
