洛杉矶市水电局（LADWP）正在安装一个SCADA系统，该系统将监控整个配水系统的水质。该项目从一个单一地点的试点系统开始，以确定其适用性和可靠性，然后再将该系统扩展到其他地点。该系统正在扩展到其他位置，并正在评估用于现有氯化设备的远程监测和控制。本文描述了系统的需求、设计、仪器的选择、评估和开发。

The City of Los Angeles Department of Water and Power (LADWP) is installing a SCADA system which will monitor water quality throughout its water distribution system. The project began with a pilot system at a single location to determine its suitability and reliability prior to expansion of the system to other locations. The system is being expanded to additional locations and is being evaluated for use in the remote monitoring and control of existing chlorination equipment. This paper describes the need for the system, design, selection of instrumentation, evaluation, and development.
