1. Overview
Enterprise intelligent energy efficiency management system is a complete set of solutions to provide enterprises with energy management, power quality and energy use safety monitoring. It includes the sources of energy (state grid, wind energy, photovoltaic power generation and other new energy sources, water, natural gas, fuel oil, etc.), the monitoring of energy use process, energy classification and sub-item energy consumption data statistics, and energy safety monitoring. This system is mainly used to help enterprises eliminate the blind area of energy consumption, improve the stability and security of energy supply system operation, and reduce the cost of operation and management for enterprises.

4. Main Functions
Enterprise intelligent energy efficiency management system includes distribution monitoring, water monitoring, new energy monitoring (Wind power generation, distributed photovoltaic and energy storage), power quality monitoring, load analysis, electricity safety, equipment power monitoring, energy consumption analysis (classified and itemized energy consumption, regional energy consumption, department energy consumption, various forms of energy consumption analysis and comparison)and other functional modules, Can realize the enterprise energy efficiency comprehensive monitoring and early warning, these function modules can choose to customize.
① Real-time warning
Real-time monitoring of leakage current, firefighting equipment, power supply status of important loads, operation status of power supply and distribution equipment, to the occurrence of abnormal power voltage, circuit residual current abnormal, cable or bus temperature abnormal, microcomputer protection device action and other situations timely alarm, remind the operation and maintenance personnel to deal with, as soon as possible to eliminate hidden dangers, to ensure the safety of people and property. The system can monitor the closing, opening and all electrical parameters of the distribution circuit in real time, and send an alarm according to the level of the event. The alarm forms are: pop-up window alarm prompt, sound and light alarm prompt.
② Operation monitoring
The system monitors the electrical parameters, cable and bus running temperature of each distribution circuit in the substation in real time, the power supply and switching state of fire- fighting equipment and important equipment, the graphical dynamic display, and the human-machine interface is friendly.
③ Analysis of energy consumption
The system supports the classified and itemized statistics and analysis function of energy consumption, which can collect energy consumption of electricity, water, gas, cold heat and industrial gas, and convert energy consumption into standard coal, at the same time, it can trace the data of energy consumption of each branch circuit, regional energy consumption and department energy consumption, carry out statistical analysis in various forms, and form an analysis report.
④ Power quality analysis
Conduct power quality monitoring for important power distribution circuits or sensitive power quality distribution circuits, including: voltage qualification rate, three-phase unbalance degree, harmonic content histogram, power factor curve display and so on.
⑤ View and statistics of system history events
Rich reporting system support timing, time - sharing and other summary statistics functions, users can freely query the energy consumption of each energy node in any time period since the normal operation of the system, and provide statistical analysis report on the energy consumption of the total energy supply loop and each branch energy consumption loop.
