Object request brokers for distributed measurement

The number of the measured parameters in a power plant is enormous, and the measurements are distributed all over the plant. Some must be measured at one site and used in other sites, and some must be measured and used in specific online demands. This article introduces components of distributed measurement systems, analyzes the framework of a system that was built at Southeast University, and focuses on specific power industry applications of the system. Examples include the application to a boiler accessory device strain test, the real-time query of the measured parameters of the generators and their auxiliary devices, and online video viewing of the monitored sites in a power plant's distributed environments.
