About the project
About Frequency Observatory
Frequency Observatory is an independent technical and educational platform created to monitor, visualise and explain power system frequency using real measurement data.
Project objective: to make power system frequency behaviour visible, accessible and easier to understand for engineers, students, energy-sector professionals and anyone interested in modern electricity systems.
What is Frequency Observatory?
Frequency Observatory is a live monitoring and technical education portal focused on power system frequency. The platform displays measured frequency data and provides educational resources to help visitors understand how electricity systems maintain balance, stability and security.
The project combines real-time data acquisition, cloud-based data storage, web visualisation and technical articles about frequency regulation, power system operation, renewable integration, inverter-based resources and the energy transition.
Why frequency matters
Power system frequency is one of the clearest indicators of the real-time balance between electricity generation and electricity demand.
Balanced system
Generation = Demand
Frequency remains close to nominal.
Power deficit
Generation < Demand
Frequency tends to fall.
Power surplus
Generation > Demand
Frequency tends to rise.
Monitoring frequency helps illustrate how the system responds to changes in demand, generation, contingencies, renewable variability, storage operation and frequency control actions.
What data is displayed?
The live dashboard displays frequency measurements captured from an independent monitoring point. The data is collected through a power quality meter, converted through an industrial communication gateway, processed by a Raspberry Pi data acquisition system and stored in a cloud time-series database.
Current measurement setup
- • SATEC PM130 Plus EH power meter
- • RS485 / Modbus communication
- • Ethernet gateway
- • Raspberry Pi data acquisition system
- • InfluxDB time-series database
- • Next.js web portal for visualisation

Educational and technical focus
Frequency Observatory is designed as both a live data dashboard and a technical learning resource. The objective is not only to show frequency data, but also to explain why frequency changes, how it is controlled and why this topic is becoming increasingly important in modern power systems.
Topics covered
- • Power system operation
- • Frequency regulation and control
- • Primary, secondary and tertiary control
- • Energy transition and renewable integration
- • Solar PV and inverter-based resources
- • Battery energy storage systems
- • System strength, inertia and grid stability
Intended audience
- • Electrical engineers
- • Power system professionals
- • Students and researchers
- • Renewable energy developers
- • Grid connection and commissioning teams
- • People interested in electricity system operation
Independence and transparency
Frequency Observatory is an independent initiative. The purpose of the portal is to provide transparent technical information and measured data to support learning, analysis and constructive discussion about power system frequency and the energy transition.
The project is not intended to replace official system operator data, market data, compliance systems or operational tools. Instead, it provides an additional educational view of frequency behaviour using independent measurements.
Data disclaimer
This portal is provided for educational, technical and informational purposes only. It is not an official system operation tool and should not be used for operational decision-making, market participation, protection settings, dispatch decisions or compliance assessment.
Data availability, resolution and accuracy may depend on measurement equipment, communication links, data acquisition software, internet connectivity and cloud services. Short interruptions, missing data or measurement delays may occur.
Future development
Frequency Observatory is being developed progressively. Future releases may include additional monitoring points, more detailed event detection, enhanced downloadable datasets, comparison between different Australian power systems and additional technical education pages.
Planned features
- • Additional frequency monitoring locations
- • Frequency event detection and classification
- • Daily and monthly data download options
- • More detailed educational articles
- • Comparison between power systems
- • Improved dashboard and mobile layout
Long-term vision
- • Support technical learning with real data
- • Create a public record of frequency behaviour
- • Encourage constructive discussion about grid operation
- • Help explain the operational impact of the energy transition
Collaboration and feedback
Technical feedback, collaboration ideas and suggestions for improving the portal are welcome. The project is intended to grow over time as more data, educational material and practical use cases are added.
