Smart Control Power Automation System

Smart Control is based on fieldbus technology, which is a real-time control communication technology that interconnects the lowest level of field intelligent devices in automation, and follows all or part of the communication protocol of ISO's OSI Open System Interconnection Reference Model. Smart control adopts the mainstream technical scheme design and open distributed network architecture in line with international standards, strictly follows the relevant international standards and industrial standards (including IEC61850 and IEC61970, etc.) of electronic information processing and power monitoring, and combines domestic self-development with the introduction of foreign advanced and mature technologies. Through the design of visual configuration environment, full Chinese operation interface, user programming interface, multi-bus support, real-time database, dual-computer hot standby, multi-clock support, distributed architecture, data report and standard equipment library, the system realizes the high efficiency, high reliability, real-time, professional and scalability, and reaches the industrial standard of power monitoring and management.

flexible control is especially suitable for remote control and management of power transformation, power receiving, power feeding, monitoring and various terminal power distribution in urban and rural substations, box-type substations, power plants, building automation, power distribution of industrial and mining enterprises, public power distribution rooms of power supply bureaus, etc. Due to the use of distributed object model, the system has a stable, reliable, fast and efficient, strong scalability, good compatibility of power professional SCADA function, set monitoring, measurement, protection, control and communication functions in one. Accidents can be found and handled at any time, reducing power failure time. Various telemetry data, closing and opening operations, switch maintenance and system accidents can be saved and printed, thus reducing the labor intensity of the personnel on duty. Through telemetry and remote control, load can be reasonably allocated, optimized operation can be realized, energy can be effectively saved, and there are records of peak and trough electricity consumption, thus providing necessary conditions for energy management.

Smart brings five tangible benefits to power system users:

1)inManagement Aspects,realize the automation and intelligence of power transformation and distribution, improve the automation level and operability of equipment, make the maintenance and management of power transformation and distribution system easier, and improve the efficiency of system operation;

2)ineconomic aspects,the realization of unattended, reducing operating costs; rapid fault diagnosis and processing, reducing maintenance costs, thereby reducing the economic losses caused by power outages;

3)inInformation Resources,realizes resource sharing through network technology and communication technology, facilitates integration with other power information systems, and adapts to the general trend of power information reform;

4)inEnergy saving and consumption reduction,reasonable scheduling and management of electrical equipment to help optimize configuration and operation, thereby effectively saving electricity and reducing electricity costs;

5)insafe operation, through equipment management can timely report the operation of equipment, extend the service life of equipment, reduce the depreciation rate of production equipment, so as to help reduce the failure rate and improve the safety of the power grid.
