Abstract

This paper presents a customized SCADA at customer side distribution automation system (DAS) for operating and controlling low voltage (LV) down stream of 415/240V by using the Tenaga Nasional Berhad (TNB) distribution system. An embedded Ethernet controller is used as RTU to act as converter for HMI to interact with digital input and output modules. RTU is the master and digital input and output modules are the slaves. RTU will initiate the transaction with the digital input and output modules. Proprietary software is used to develop algorithm for the controller and to develop HMI for monitoring and controlling functions for the operator. The SCADA system software includes software modules such as graphic editor, database setup, alarm configuration, trending tools and communication setup. HMI monitoring system is correctly showing the fault point and generates the correct alarm messages for the operator to be acknowledged. The SCADA system developed provides automatic fault isolation, monitoring and controlling functions for the operators and data collection for future analysis.

为低压配电自动化系统定制SCADA系统

本文介绍了一种客户端配电自动化系统(DAS)的定制SCADA，用于使用Tenaga Nasional Berhad (TNB)配电系统对415/240V下游低压(LV)进行操作和控制。采用嵌入式以太网控制器作为RTU，作为人机界面与数字输入输出模块交互的转换器。RTU是主模块，数字输入和输出模块是从模块。RTU将启动与数字输入和输出模块的事务。使用专有软件为控制器开发算法，并为操作员开发监视和控制功能的HMI。SCADA系统软件包括图形编辑器、数据库设置、报警配置、趋势工具和通信设置等软件模块。HMI监控系统正确显示故障点，并产生正确的报警信息供操作人员确认。开发的SCADA系统为操作人员提供自动故障隔离、监测和控制功能，并为未来分析提供数据收集。
