洛杉矶水电局（DWP）是美国最大的市政公用事业机构，在南加州465平方英里的范围内为360多万人供水和供电。在自然干旱的南加州地区，供水和配水日益复杂，这促使DWP安装了一个主要的SCADA（监控和数据采集）系统。DWP对许多SCADA系统进行了评估，并承包开发了一个系统，该系统将采用该技术来监测和控制其大型配水系统。 这项工作的最终成果是洛杉矶水系统数据采集和控制（LAWS-DAC）系统于1992年6月投入使用。本文介绍了DWP水系统SCADA项目，包括系统要求、测试和安装、培训、系统配置和未来考虑。

The Los Angeles Department of Water and Power (DWP) is the nation's largest municipally-owned utility, delivering water and power to more than 3.6 million people, over a 465 square mile area of Southern California. The ever increasing complexities of supplying and distributing water in the naturally arid Southern California region prompted DWP to install a major SCADA (Supervisory Control and Data Acquisition) system. DWP evaluated many SCADA Systems and contracted for the development of a system that would adapt the technology to monitor and control its large water distribution system. The ultimate result of this effort, the Los Angeles Water System Data Acquisition and Control (LAWS-DAC) System, was placed in service in June 1992. This paper describes the DWP water system SCADA project including system requirements, testing and installation, training, system configuration, and future considerations.
