| 摘要: |
| 为改善电磁型备用电源自投装置接线复杂、功能僵化、误动等缺点，提出了一种新型的微机型备用电源自投装置。它根据主接线特点，利用软件的智能性，可对不同主接线方式的发电厂和变电站自动进行模式识别，而不需要继保人员频繁操作。该装置制作成本低、运行可靠性高、功能齐全、使用方便，这些都是电磁型备用电源自投装置无法比拟的。试验和运行证明，模式自识别方式是可行的，以此设计的微机型备用电源自投装置具有良好的性能和实用价值。 |

| Abstract: |
| Electromagnetic type automatic switching device for spare power source applies logic circuit of relay,which is complex and inflexible.When the operational mode of power substation or power plant changes,the device may run incorrectly.A new scheme of mode adaptive microprocessor based automatic switching device for spare power source is introduced to improve the situation.With the intelligence of software and based on the analysis of main line connection,it can automatically recognize the operational mode of power substation or power plant,the relay operator's intervention is not necessary.The low cost and high reliability of the new device is not comparable by the electromagnetic one.Test and operation prove that the new device is practicable with good performance. |
