With the rapid pace of urban construction and the improvement of the living standards of residents, the demand for electricity is increasing day by day. Power generation system is the basic power source of urban construction, production development and household electricity consumption. The power plants in China are mainly composed of thermal power plants, wind power plants, hydropower plants and optoelectronic power plants, while thermal power plants are the most primitive and occupy the highest proportion. So it is very important to strengthen the safe production of thermal power plant.
For a thermal power plant, the principle of power generation is that circulating water is heated by coal to produce steam that is piped to the steam turbine. The steam turbine rotates at high speed and drives the generator to generate electricity. The effective monitoring of the steam pipeline transmission process includes flow and pressure. Monitoring of temperature and other monitoring parameters is very important. Operators need to ensure the operation of the integrated monitoring system from the central control room to protect the whole system in a high level of safety. When the relevant parameters deviate from the normal range. The system sends the signal to inform the operator to take the corrective action. The network realizes the centralized monitoring distributed in the local scattered pipeline station, may on-line real-time accurate palm Grasp the running state of each pipeline, complete the emergency alarm, and automatically close the valve to avoid serious losses, realize the overall centralized management of steam pipes in thermal power plants, facilitate the optimal allocation of resources. For the full realization of enterprise information laid the foundation.
