Storage, retreival and process of continuous streaming data in a Wide Area Frequency Measurement System and further analysis to generate the flags and alerts.
Power System Network is continuously subjected to disturbances in the form of sudden load and generation changes. These disturbances give rise to oscillations in the rotor angle which are also seen in the frequency. To study these oscillations wide area frequency measurement setup is implemented in this project. The setup are strategically placed in five different places in India and are time synchronized via Network Time Protocol (NTP). The frequency is measured every 20 ms and is time stamped and send through
internet to a server in IITB.
The server program which is continuously receiving the packets, checking the correctness of packet information, doing the insertion in database according their time and displaying it on the web.
In ‘Wide area frequency measurement system’ frequencies measured at different places in India are sent to a IITB Server. Frequencies are measured by sensors at every 20 ms. Local frequency measured is stamped with the time and place and sent to IITB Server.
The IITB server is continuously listening for the packets on UDP port 6000. When a packet is received, it extracts the data and writes it in a file. A separate file is created for each sensor and when any file reaches its maximum a new file is created for each sensor with incremented serial number. Plotting of this data is done offline.
