PowerSYS3.0 Intelligent Monitoring System

1 Overview
The Power SYS 3.0 intelligent power quality monitoring system is a specialized, highly automated, easy-to-use, high-performance, and highly reliable power management system developed according to user requirements and following the standard specifications of the distribution system. It is suitable for high and low voltage distribution systems. Through telemetry and remote control, it can reasonably allocate loads, achieve optimized operation, effectively save energy, and have records of peak and off peak electricity consumption, providing necessary conditions for energy management. At the same time, electricity is measured separately according to the electricity consumption of lighting sockets, power, air conditioning, and special electricity, providing a basis for energy conservation audits of enterprises and institutions.

With the rapid development of the economy, energy scarcity and environmental degradation have received close global attention. Energy is an important foundation for the development of the national economy. In order to respond to the national call and take the path of sustainable development, energy conservation and consumption reduction are the primary tasks. Among them, electricity consumes a relatively large amount among all energy sources, and the unified management of electricity is particularly important. Only accurate and reliable measurement of electrical energy can truly save energy.

2 System Structure

The Power SYS 3.0 energy management system can measure the energy consumption of low-voltage equipment separately. Its software runs on the Windows operating system, including Windows 2000, Windows NT, Windows XP and other Windows series operating systems. In addition to good compatibility with the company's independently developed instruments, the system also supports hundreds of various hardware devices, including popular boards, comprehensive protection, instruments, PLCs, etc. Support various commonly used power communication protocols, such as CDT protocol issued by the Ministry, POLLING, 1801, 101, DNP and other power protocols.

According to the relevant requirements of the country for electricity measurement, this system measures the electricity consumption by item, including:

(1) Electricity consumption for lighting sockets: used for indoor equipment such as lighting and sockets in the main functional areas of buildings. Mainly including lighting and socket electricity, corridor and emergency lighting electricity, and outdoor landscape lighting electricity.

(2) Air conditioning electricity: mainly includes electricity for cold and hot stations and electricity for air conditioning terminals.

(3) Power consumption: mainly includes electricity for elevators, water pumps, and ventilation fans.

(4) Special electricity usage: mainly includes information centers, laundry rooms, kitchens, restaurants, swimming pools, gyms, or other special electricity usage.
