Description

Technical Field

[0001] This application relates to the field of generator controller testing technology, and in particular to an intelligent testing system for high-voltage DC generator controllers. Background Technology

[0002] Currently, aircraft generator controllers, as the central hub of aircraft power distribution and protection systems, play an invaluable role in ensuring the safe, stable, and efficient operation of aircraft power networks. High-voltage direct current (HVDC) generators, with their superior continuous power supply efficiency and strong environmental adaptability, have become an indispensable key component in the power industry. Especially in the aviation field, facing complex and ever-changing operating conditions, generator controllers must precisely and dynamically regulate the generator to achieve optimal performance. For functional performance testing of HVDC generator controllers, the most important aspect is accurately simulating the interaction parameter configuration between the controller and the generator to verify the controller's core functions such as voltage regulation, power distribution, and anomaly protection. Currently, a common approach is to use temporary test environments in ground-based laboratory settings to simulate the interaction between the generator and controller, thereby optimizing and verifying control strategies and control interaction parameter configurations, and ultimately achieving functional performance testing of the generator controller.

[0003] For testing high-voltage DC generator controllers in the aviation field, the common domestic approach is to construct ground-based laboratories, using industrial measurement and control equipment combined with a physical generator to create a highly simulated test environment. While this approach effectively reproduces the generator's high-voltage interaction parameters and evaluates the controller's performance response under extreme conditions, its inherent space limitations severely reduce the flexibility and convenience of testing, resulting in long testing cycles and low efficiency. Furthermore, because the testing process heavily relies on manual operation, it not only increases the risk of human error in test results but may also damage internal system components of the generator controller due to differences in operator skill levels. Under these conditions, the cost of testing the generator controller's functional performance is high, undoubtedly increasing product development cycles and financial pressure on enterprises.
