Power Quality Monitor System

Author:Sifang Sanyi    Date:2013-12-24 18:52

System Function

Data Acquisition Function

Adopt a consistent storage format of power quality on different monitoring spots to build management system on consistent data basis.

Integrated Query Function

Construct power quality data center, and on this basis construct integrated query system facing management layer. 

Establish power quality auto-report system to increase working efficiency.

Adopt query interface based on IE browser, so power quality technicians at all levels can enter relative monitoring spot to check power quality data and master power quality condition.

Data Analysis Function

Construct monitoring network database and rule database founded on national standard. Carry out statistical analysis according to different power quality indexes. Do statistical analysis of real-time and historical datum assembled by the unit and form various report forms, graphical chart, pie chart, bar graph. The statistical analysis results can be exported various patterns, such as RTF document, EXCEL sheet, HTML document, PDF document, file document, JPG picture. It also supports edit and printout function.customer harmonic preternormal quantitative check function

Control the operating condition of measuring circuit active power meter. When the customer harmonic current or voltage exceeds the limits, the monitor will control intermediate relay and start charging electric meter; when not exceed, the meter will return automatically. Therefore it can realize the power measuring when the harmonic exceeds the limits.

Lower computer remote parameter setup and advisement function

The device on monitoring spot can  be revised remotely by the manager or the people who have the authority.

Website information release and interaction function

Website can provide public information exchange platform, such as announcement, forum to be used for professionals’ technical exchange

System maintenance function

Provide rights assignment function for system manager. The manager can authorize and do other security control to users conveniently according to personnels’needs. Identification and zone location of harmonic disturbance sourceConstruct data statistical analysis system according to the monitoring datum. It can realize identification and zone location of harmonic disturbance source. Moreover, it can further provide relevant information for the control of power quality and give proposal to solve power quality problems.

Construct management system of power quality by adopting GPRS or TCP/IP agreement.

Meaning of constructing power quality monitoring system

Combine on-line monitor with technological supervision of power quality and strengthen the management and monitor of 

network power quality. Thus the monitoring and management function of network power quality which is forms by province as 

a unit operates normally in consistent network program.

Construct power quality data center and provide power quality index to society. 

Construct Intranet throughout the entire province. Construct integrated query system facing managers on the basis 

of power quality data center. Meanwhile construct power quality auto-report and summary system facing the whole province 

to increase working efficiency.

Construct query system in power supply enterprise, thus we can get to know the operation condition of the power network 

through query about various datum and report forms on the internet. 

We can assess and simulation analyze the whole power supply network and give renovation suggestion if the system  operates successfully.
