针对配电网自动化工程中系统集成的一个实际困难 ,即远动设备经常与主站 SCADA系统所采用的协议不同 ,提出了远动设备的即插即用问题和解决该问题的一种可行方案 ,即采用人工神经网络建立起协议的特征信息与协议类型之间的非线性映射关系 ,来完成设备协议类型的识别 ,并对实际数据的获取、特征码的提取、样本的编制、训练次数、通信速率的自动识别以及新协议的添加等关键问题给出了处理方法。此外 ,还简要介绍了采用该方案实现对远动设备即插即用支持的多协议智能通信控制器的软、硬件构成和实现方法。在当前没有远动设备即插即用标准的情况下 ,文中所提出的方案在这方面做了有益的尝试 ,并取得了较为满意的效果。
Aiming at the practical difficulty of system integration in distribution network automation engineering, that is, the remote equipment is often different from the protocol adopted by the SCADA system of the main station, a plug and play problem of the remote equipment is proposed and a feasible solution to the problem is proposed , That is, the artificial neural network is used to establish the non-linear mapping relationship between the characteristic information and the protocol type of the protocol, so as to complete the identification of the device protocol type and obtain the actual data acquisition, signature extraction, sample preparation, training times, The communication rate of automatic identification and the addition of new protocols and other key issues given treatment methods. In addition, it also briefly introduces the software and hardware configuration and implementation method of the multi-protocol intelligent communication controller adopting the scheme to realize the plug-and-play support for the remote equipment. In the current situation that there is no plug-and-play standard for telecontrol equipment, the scheme proposed in this paper has done a useful attempt in this respect and has achieved satisfactory results.
