Embodiment Construction

[0008] The invention provides a general test interface platform for the main control of the wind turbine generator set, including a signal conditioning circuit, the signal conditioning circuit is respectively connected with the I / O interface and the real-time simulator interface of the main control system through the D-type data interface connector. The signal conditioning circuit includes a digital signal conditioning unit to convert 24V high and low level signals into 5V TTL signals, and the signal conditioning circuit also includes an analog signal conditioning unit to convert a 4-20mA current signal into a 0-10V voltage signal. The interface of the real-time simulator is specifically a DSP interface or an FPGA I / O interface. Among them, there are at least two digital signal conditioning units, and at least two analog signal conditioning units.

[0009] The using method and working principle of the present invention are:

[0010] 1. The digital signal conditioning adopts p...

Abstract

The invention relates to a general test interface platform for master control of a wind generating set. The system is characterized in that the system comprises a signal conditioning circuit, the signal conditioning circuit is connected with an I / O interface of a master control system and a real-time simulation machine interface through a D-type data interface connector, and the signal conditioning circuit comprises a digital signal conditioning unit so as to convert 24V high and low level signals into 5V TTL signals; the signal conditioning circuit further comprises an analog signal conditioning unit so as to convert a 4-20 mA current signal into a 0-10 V voltage signal. The invention provides a plug-and-play signal universal interface platform for the detection and maintenance of the main control system, which can realize the detection and maintenance of different types of main control systems, obviously improve the maintenance efficiency, reduce the cost and save the space of a test site.

Description

technical field [0001] The invention relates to a general test interface platform for the main control of a wind power generating set. Background technique [0002] As a kind of clean energy, wind power accounts for an increasing proportion of the total energy. However, with the increase of the service time of wind turbines, the failure of wind turbines occurs frequently, especially the main control system failure of wind turbines, which seriously restricts the sustainable development of wind power and the economic benefits of wind power enterprises. Hardware-in-the-loop (HIL) testing technology, as a highly reliable testing technology, has a good application prospect in the main control testing of wind turbines, but it often requires a conversion interface including a signal conditioning circuit to connect the system under test and the real-time simulator. Therefore, it is very necessary to build a general interface platform for the hardware-in-the-loop test and maintenanc...
