Measurement of electrical energy sub items in electronic factory substation

Measurement of electrical energy sub items in enterprise substationsInstall a set of Acrel-1000 substation comprehensive automation system monitoring screen and an Acrel-2000Z power monitoring system monitoring screen in the electrical monitoring room. Real time data of secondary equipment such as microcomputer protection devices and power quality is collected through communication management machines and network switches to achieve comprehensive power monitoring and automation management of the entire power supply and distribution system in the plant area. And configure an integrated power supply system to provide stable and reliable power for the operation of important equipment such as circuit breakers, secondary equipment, and monitoring hosts in the entire substation.

AcrelEMS Enterprise Microgrid Energy Efficiency Management Platform adopts B/S architecture and integrates Acrel-1000 Substation Integrated Automation SystemandAcrel-2000Z power monitoring system,Enterprise Microgrid Energy Efficiency Management PlatformImplemented fromOverall monitoring of 35kV distribution to 0.4kV power consumption side, providingSubstation integrated automation system, power monitoring, power quality monitoring, electrical safety protection, and power statistics. It provides significant assistance to the electricity management of enterprises.

System functional requirements:

Substation Integrated Automation SystemMonitor the power consumption of the 35kV medium and high voltage side of the enterprise through a system diagram, and refresh the data in real-time.

Power monitoring: monitoring enterprisesProvide monitoring of the power consumption on the 0.4kV low-voltage side, including monitoring of the distribution room, monitoring of the reactive power compensation cabinet, and power reporting.

Power Quality: Provide steady-state monitoring, harmonic spectrum, steady-state curve, and harmonic curve for power quality detectors,SOE events and other parameters.

Electricity statistics: Provides functions such as electricity consumption collection, electricity consumption statistics, time-based electricity consumption statistics, electricity consumption analysis on a month on month basis, and grouped electricity consumption statistics.

The comprehensive automation system of a substation refers to a combination of interrelated units that achieve a given goal by performing specified functions. The comprehensive automation system of a substation uses advanced computer technology, modern electronic technology, communication technology, and information processing technology to recombine and optimize the functions of secondary equipment in the substation, monitor and measure the operation of all equipment in the substation, and upload the main data to the local dispatch platform. At the same time, it receives control instructions from the dispatch end to achieve power regulation in the substation.

The comprehensive automation system and power monitoring system of the substation can be divided into three layers: on-site equipment layer, network communication layer, and platform management layer.

On site equipment layer: including microcomputer protection, intelligent control, multifunctional instruments, measuring instruments and other equipment, used to collect electrical operating parameters, switch status, electrical contact temperature and other data in the distribution cabinet inside the station, and at the same time, respectivelyMultiple configurations of 35kV substations and 10kV substationsInstall a DC power supply to ensure a good operating environment for on-site equipment.

Network communication layer: includingANet-2E8S intelligent gateway. The gateway actively collects data from on-site equipment layer devices, and can perform protocol conversion, data storage, and data collection through a data acquisition box (built-in intelligent gateway) in a dispersed 10kV substation. The data is uploaded to the communication room substation comprehensive automation monitoring system platform through optical fiber; At the same time, the gateway acts as a remote communication device, collecting data from on-site equipment and encrypting it vertically through a switch before uploading it to the dispatch network.
