摘要:
为了增强变电站二次测试智能化水平，提高测试效率，提出了一种基于智能语音识别的电力二次测试系统。采用一种针对电力专用词库的二次语音识别引擎，设计了基于离线识别模式的嵌入式测试系统。在实验室与现场，利用该系统分别实测了智能终端、保护装置、合并单元等设备。实测结果表明，电力专用词汇语音识别引擎提高了整体识别率和稳定性，且该测试系统的语音操控能够准确无误地完成整个测试过程，增强了电力二次测试仪的操控性、灵活性和易用性。

Abstract:
In order to enhance the intelligent level of substation secondary test and improve the test efficiency, the solution of smart substation testing based on intelligent speech recognition is proposed. A secondary speech recognition engine for power special lexicon is researched and the embedded system design of off-line recognition mode is given. In the laboratory and in the field, the intelligent terminal, protection device, merging unit and other equipment are tested by using the system. The experimental results show that the power special lexicon speech recognition engine significantly improves the overall recognition rate and stability and the speech control of the test system completes the whole test process accurately and correctly, which greatly enhances the maneuverability, flexibility and ease of use. This work is supported by Science and Technology Project of State Grid Corporation of China (No. 5211HZ1700A).
