Improvement method of interface circuit of blower controller real-time testing system

Abstract

The invention discloses an improvement method an interface circuit of a blower controller real-time testing system. The method includes the steps that an input circuit of a GTDI (digital quantity input) card of an RTDS (real time digital simulator) is improved, a resister pack R is connected between an external power supply and a diode in series, and then the voltage of the external power supply is matched with the voltage of the output level of a tested blower controller; simulation / digital input / output cards of the RTDS are integrated into a single switch cabinet, and the external power supply mode of the working voltage of the input / output cards and the external power supply mode of the voltage of the external power supply are unified by adjusting the voltage of the external power supply of the GTDI card. According to the method, after the input circuit of the GTDI card of the RTDS is improved, the interface circuit can be conveniently and effectively adjusted according to the voltage of the output level of the tested device; the design of the switch cabinet is adopted, testing wiring operation is greatly simplified, intermediate links are reduced to the maximum degree, attenuation in the cable transmission process is reduced, and testing accuracy and error correcting capability are improved.

Description

technical field [0001] The invention relates to an interface circuit improvement method of a real-time test system for a fan controller, belonging to the technical field of electric power testing and measurement. Background technique [0002] With the intensification of competition in the global energy field, countries around the world are paying more and more attention to the implementation of their own sustainable development strategy. As one of the core technologies of this strategy, the research on distributed power generation and energy supply technology has attracted more and more attention from all countries. Many developed countries such as the European Union, the United States, and Japan have placed distributed power generation technology in a very important position in the process of energy structure adjustment. Wind power is currently the new energy with the most mature technology, the most conditions for large-scale development and the most promising prospects ...

Problems solved by technology

However, these tools have common defects: first, the calculation speed is slow and cannot meet the requirements of real-time calculation; second, they do not have the ability to interact with actual devices, and cannot carry out closed-loop test research on power automation equipment

[0004] In order to realize the closed-loop test of the fan controller, it is first necessary to ensure the effective interaction between the controller and the digital information of the RTDS, and each digital input / The output cards all need an external power supply to provide working voltage, which are 5V / 24V respectively, and cannot be compatible with the external digital output voltage under test
