HMI-based power industry program

Electricity is the basis of the modern economy industries, all modern electronic devices based on the normal operation to ensure sustainable, efficient supply of electricity to the power sector is the focus of attention. Automation and control from the point of view, the power industry with other industries when compared with decentralized control, unify the characteristics of a joint operation. Systems involving power plants, substations, mobilization centers; hair, lose the power distribution system integration, the system includes a variety of independent systems and the control of a joint power grid protection technology, communications technology and operation management technology.

Vertical and horizontal integration of science and technology hardware and software system platform in the power plant, computer control, substation automation, power grids dispatching automation, power load management, electricity and other fields of scientific research and experiment in real-time collection and control system (SCADA) in a wide range of applications. Power grid operation in real-time control systems, including automatic generation control system of power grids and to support its operation of dispatching automation systems, power plant computer monitoring system, and centralized control station substation integrated automation systems, relay protection and security of power grids and other automatic device, HMITECH products and stable operation of power system, provide an effective guarantee.

For example, the power plant automation systems, the total control layer are mainly composed of two parts: First, control devices, first the background SCADA system. Power unit measuring electrical equipment through the intelligent (IED), for example to HMI as the central control unit for monitoring and control of AGC screen, and the step-up station-one correspondence between layer monitoring and control unit to complete the power plant unit monitoring and control, through the Industrial Ethernet, so that stations information is shared with the background of China Science and Technology Distributed SCADA system. Monitoring and control through HMITECH man-machine interface screen display TPC control information, such as the booster station operating parameters and the Knife, switches, electrical equipment operation and be able to achieve local control and remote control operation. System requirements have very good scalability and interconnection with other systems, the China Science and Technology provided by man-machine interface provides a standard hardware platform Fieldbus Communication Interface, embedded industrial-grade configuration of distributed software, the realization of the system within the same power plant DCS , SIS, CIS and other systems of information exchange.
