A MICROCOMPUTER BASED RELAYING PROTECTION DEVICE FOR GENERATOR BASED ON μC/OS-II

XU Tian-qi1,YOU Da-hai2,LI Cheng3,WANG Yang-guang2,WANG Jian2 (1.Department of Physics and Electric,Yunnan Nationalities University,Kunming 650031,Yunnan Province,China;2.College of Electric and Electronics Engineering,Huazhong University of Science and Technology,Wuhan 430074,Hubei Province,China;3.Baoding Tianwei Baobian Electric Co. Ltd., Baoding 071056,Hebei Province,China)  
μC/OS-II is the kernel of a source-code publicized real-time operating system and is portable, reliable and stable. A μC/OS-II based embedded protection device for generator is presented and the necessity and application value of leading real-time operating system into microcomputer based relaying protection is illuminated. On the basis of explating μC/OS-II to digital signal processing (DSP) chip TMS320VC33, the μC/OS-II is integrated with high performance floating point DSP chip, then according to the protection principle the protective scheme of the presented protection device, whose multi-functions are implemented by dividing different tasks, is proposed. Test results of the presented protection device show that the embedded generator protection device using μC/OS-II is reliable, flexible and easy to maintain.
