I-7000 Series Modules Applied in Computer-based Remote Dispatching System for Thermoelectric Plant
A group power plant, which is a heating power plant by utilizing steam turbo-alternator to generate electricity, consists of four power boilers, three generator systems and two common systems. With so many huge facilities and a number of associated and distributed parameters that need to be monitored, it is very difficult for these plants to coordinate these operating parameters in order to make the whole system to run under high efficiency low loss and safe operation. The nine facility operation rooms of the system are distributed from tens to hundreds of meters apart from each other and the central dispatching room of the power plant is 500 meter away from the field. The command and dispatching of the whole production can only depend on telephone system instead of field monitoring, resulting in fake operation data, concealed failure and disobey of dispatching instructions.The system always operates with low efficiency and many accidents.
In order to improve production efficiency and reduce cost by enhancing dispatching and management level, based on the I-7000 series remote measurement modules network, we developed a computer based remote dispatching system under LAN platform for this plant.
It is a computer based industrial monitor and communication network including complicated systems and functions with high real-time features. This paper only discusses some important issues during the use of 1-7000 series modules in lower layer of the monitoring network.
