摘 要：电力计量在电力系统发送、输出、供电过程中有着重要作用，电力计量回路一旦出现故障，就会严重影响电力供应。为此，电力系统需要消耗大量的人力物力资源对员工进行定期培训。传统的现场培训模式不仅效率低下，而且存在安全隐患，使用虚拟现实技术可以解决这一问题。首先生成计量系统常见模型，然后搭建三维教学环境，使用语音技术设计交互模式和考试模式。该系统可降低80%的培训时间成本，提高了培训效率，方便学员进行系统培训和考核。

Abstract： In electric power system， electric power measurement plays an important role in the process of electric power transmit， electric output and electric supply. Once the electric power metering circuit breaks down， peoples daily life will be seriously affected. In order to address the above problem， electric power department takes large amount of resources to carry out training tasks periodically. The tradational on-the-job training pattern is not only inefficient but also has security threat. A training system for simulating electric metering circuit by means of virtual reality technique has been proposed. First， the common model of the power metering system is generated to construct the three-dimensional teaching environment. And the voice technology is used to implement the interaction pattern and exam pattern. The designed training system can improve the teaching efficiency and reduce 80% of time cost.

Key Words： electric power metering circuit; virtual reality; simulating operation; training system

電力计量是电力系统发送、输出、供电工程中至关重要的环节，电能计量的准确性决定电能是否能合理调度，满足生产与生活需求[1-2]。电能计量不但是电力市场交易和营销的基本技术支撑与基础数据来源，同时也是生产技术单位判断设备是否经济运行的基础数据来源。通过准确的计量核算，可以分析电力变压器等电网设备损耗是否超过允许值，对高损耗电网设备可进行处理或更换，降低单位能耗[3-4]。然而在现实生活中，由于设备的自然损耗、人为破坏、自然灾害等因素，电能计量回路故障时有发生。为了在发生故障后迅速恢复正常供电，电力部门需要耗费大量的人力物力进行培训工作。
