The current status of 'Introduction of the synchrophasor-based monitoring and control system (WAMS/WACS)' project and further steps to implement the second stage of the project were discussed during the video conference held at the regular meeting of the Managing Committee with the participation of Askerbek Kuanyshbayev, Project Sponsor.
Serik Zharkinbayev, Project Manager, spoke about the work performed under the first stage of the project to implement the monitoring system.
Currently, WAMS (Wide Area Measurement System) equipment has been installed at the Company’s substations and dispatch centres in Astana and Almaty. The WAMS architecture covers 14 substations in the direction of North-South Kazakhstan transit including 500 kV Shymkent and 500 kV Zhambyl substations. They are equipped with PMU-vector measurement devices, GPS clocks and switches ensuring the synchronization of measurement data, which are sent to servers of the National Dispatch Centre (Astana), and in parallel transmitted to the regional dispatch centre in Almaty. The information is duplicated in order to provide backup resources.
Measurement data are monitored using Phasor Analytics and Phasor Point software.
The users of the first level (substation workers) and second level (dispatchers) have been trained and familiarized with the equipment. Currently, all components of the WAMS monitoring system undergo the comprehensive testing.
Also, the meeting approved the updated Charter of the project and discussed the ways to develop algorithms and create the WACS (Wide Area Control System) automation on the basis of synchrophasor measurements of the monitoring system.
The project shall be implemented in two stages and shall maximize the use of capacity by managing electrical networks in real time. It shall allow assessing the state, analysing stability margins and effectively use the capacities of the power grid. Project implementation period: 2018 – 2020.
