摘要
电力负荷管理终端和各种表计应用越来越广泛,但目前没有集现场终端和各种表计的各项技术指标及功能于一体的检测装置。本文介绍一种采用通讯控制技术,能仿真配电网的各种运行状态,将配变综测仪、网络电能表、大用户终端、多功能电能表的各项功能检测集成于一体的装置,其功率源采用数字PWM技术,减少了装置重量和体积,提高了效率。
The application of terminal and meters in DMS is more and more popular, but now there is no integral device which can gather the function of terminal meter and other meters. This paper will introduce a device utilized by the modern communication technology, it can imitate kinds operating state of distribution network, and integrates all the measuring features for the instruments including the distribution transformer terminal, networked power meters, commercial customer terminals, and multi-function powers meters. The emulational source of the device is armed with the digital PWM technology, which reduces the weight and size of the device but increases the efficiency. This device is used in Jiangxi province successfully.
