摘要
介绍了一种基于电子式电压互感器的新型微机自动同期装置,阐述了同期装置的软件算法和电子式电压互感器的简单原理,并从硬件和软件两个方面来给出了新型同期装置的设计方案,实验结果表明能够实现发电机平滑并网。由于其基于电子式电压互感器,并在软硬件方面采用新技术,因此该装置与以往的同期装置相比:抗干扰能力更强、精度高,硬件结构简单,在高电压等级时,也不失准确性。
A new microprocessor automatic synchronizer based on the electronic voltage transducer is presented, the software algorithm and principle of electronic voltage transducer are expounded, and the design plan of the new synchronizing device is given according to the hardware and the software. Simulation results show that generator can parallel in the power grid. Basing on electronic voltage transformers and using new technology in hardware and software, the new device has stronger anti-jamming ability, better accuracy, and simpler hardware structure than the old ones have. When the voltage step increases, the accuracy of the new device will not lose.
