Construction scheme of energy consumption management and control center in high energy-consuming plant and development of on-line monitoring system

The energy management system can be used in government management departments, enterprise production management departments, measurement management departments and so on. The energy management system can automatically and remotely copy the energy data of enterprises, such as electric energy, hydropower, thermal energy, etc., greatly saving the labor cost of manual meter reading, real-time collection of electricity, water, gas and other energy data, and collation, storage and analysis of the collected energy data. Development of Energy Management and Control system in Source, China and Switzerland

Real-time grasp the specific whereabouts of energy consumption, to achieve online energy monitoring, energy data analysis, equipment management, early warning and other functions. Key energy-using enterprises can also report their energy status reports for the current quarter or year to the municipal or provincial energy-saving supervision centers through the system.

Core of intelligent energy management system

1. Rational use of space area, construction of photovoltaic power stations or wind power generation, spontaneous self-use or surplus access to the Internet, and the use of state and local subsidies to create economic benefits for enterprises and reduce industrial and commercial capacity, electricity and energy costs. The Fed energy system can smooth the load fluctuation caused by intermittent new energy generation, improve the daily load rate of the system, and can be used as a reserve capacity in the power system to participate in frequency modulation, peak regulation and improve the utilization rate of power generation equipment. improve the overall operation efficiency of the power grid.

2. Realize controllable and adjustable key equipment: controllable and adjustable power factors of energy storage converter and photovoltaic inverter, improve power grid environment in the factory, avoid fines due to excessive power factors, and higher power factors can also enable factories to reduce power loss of lines and equipment. The charge and discharge of the energy storage battery can be adjusted and controlled, making use of the peak-valley price difference of the electricity charge, the electric energy is stored from the power grid at night when the electricity consumption is low, and released from the storage battery at the peak of electricity consumption during the day, which helps enterprises to manage the peak amount of electricity, reduce the peak electricity charge of the time-sharing price of the factory, and the qualified enterprises can also save the cost of capacity.

3. Emergency standby power supply: when there is a power outage in the power grid, the microgrid energy storage system is composed of solar energy, wind power, oil engine, energy storage battery and other power generation methods to provide uninterruptible power supply for key loads.

4. Load analysis and management: using various sensors and watt-hour meters, analyze the effects of various parameters and variables on energy (such as weather, output, etc.), manage energy consumption in all aspects of production and operation, find the inefficiency of equipment in production and waste in the process of energy use in enterprises, and establish energy economic indicators (energy consumption per unit output, energy consumption per unit area) needed by various enterprises. Take into account the impact of energy prices and costs in production, help enterprises to strengthen energy consumption, energy accounting management, and make enterprise management more scientific.
