System login requires users to enter the user and login password, the system can be set according to different users of different levels, achieve different functional classification management.
Overview of Energy Consumption
After the system is logged in, the total energy consumption of the enterprise in different periods can be displayed, such as the daily energy consumption data, monthly energy consumption data, broken line graph of energy consumption data in the current year, and the proportion of different energy consumption.
Energy Consumption Real-time Data Monitoring
The system platform can automatically collect energy consumption data: the system can automatically collect energy consumption data through the collector according to the set collection cycle, and the software can automatically complete the data collection task through the data acquisition driver.
This module mainly monitors and displays real-time data of the equipment, such as voltage, current, active power, reactive power, power factor and so on. At the same time, the load rate of the equipment is monitored, so that the user can control the transformer load state in real time and adjust and optimize the load in time, which can be used as a reference for reporting the demand.
Energy Consumption Online Monitoring
The system platform can display the energy consumption, load curve and energy performance parameters of every 15 minutes of the organization, region, production line and main energy-using equipment in real time。Energy consumption monitoring: the system displays the energy consumption, load curve and energy performance parameters of the organization, region and main energy-using equipment in real time (previous period)
Energy Performance Management
The system platform can conduct classified statistics and balance according to the energy-using attributes, reflect the efficiency of all kinds of energy production, conversion, transmission, distribution and use, prepare reports, and manage and analyze related energy consumption indicators.
According to the requirements of the energy management system, the energy performance of different levels and different types of energy can be counted, analyzed and managed. The system can set the benchmark value, index value and benchmark value of energy performance parameters, compare the current energy performance with the benchmark value, index value and benchmark value, and compare the year-on-year and sequential energy performance.
Power Quality Management
The system platform can collect all kinds of power quality information and view the actual data of energy supply quality in real time, so as to provide basic data for analyzing the deviation of energy supply quality. Such as voltage harmonic, current harmonic, voltage imbalance degree, frequency deviation and other parameters.
Power Comprehensive Energy Analysis
The system platform can conduct multi-dimensional analysis and comparison of energy consumption, energy performance and energy quality, so as to facilitate energy managers to find differences and analyze causes. The energy utilization efficiency of key energy-consuming equipment in different periods was analyzed.
Power Electricity Primary Wiring Diagram
This module mainly displays the real-time data of a power distribution room in the form of a system diagram, so that the on-duty personnel can timely understand the power supply situation and find potential problems in time. A drawing support stepless scaling, regardless of the size of the drawing can be easily viewed.
System reports can generate daily reports, monthly reports, annual reports and other reports, can also query reports according to the custom date, according to customer requirements to customize all kinds of reports. The system analysis can customize the analysis object, and carry out year-on-year and month-on-month analysis. The system automatically generates energy utilization reports.
Internal report: fill in the internal report of the company.
External report: fill in the external report of the company (submit to the external report).
This module can mainly display the trend chart of all kinds of historical data, such as voltage history, current, power, energy consumption and so on.
The value defined by system alarm can be the basic measurement value (power parameter value out of limit, energy measurement value, state value, network state), or the energy performance parameter calculated by the system, or the calculated amount.
Meter alarm：Set the alarm value and alarm。
Energy performance alarm: set the alarm value and alarm. The alarm value can be fixed or varying with the output.
The system can predict and analyze the energy demand. At present, the two-part electricity price calculation method is adopted to assist enterprises to develop a suitable demand forecast, which will help users to reasonably save electricity costs. This system will according to the previous electricity data, combined with the current user electricity situation, reasonably give the next month's electricity demand, help the user relatively accurate demand report, so as to achieve substantial savings in electricity costs.
The system platform can monitor and analyze the utilization, running status, abnormal status and working efficiency of important energy-using equipment. Analyze the efficiency of transformer, air compressor and main electric equipment in the enterprise, adjust the electric load according to the load rate of the transformer, and make the transformer in the optimal working state.
The system platform can analyze the online power rate of the enterprise, provide data support for the enterprise governance power factor, help the enterprise to have a targeted governance power factor, avoid the equipment waste and force rate penalty.
