In each station a pair of SterPMUs are monitoring an incomer and one selected feeder. Authorized users from Tractebel, OETC and distribution companies where PMUs are installed have access to real time measurements and hysterical recordings. Event triggering system with mail and SMS alarming was configured as a part of the campaign.

WAMSTER-2 project has received funding by the Croatian Ministry of Enterpreneurship and Crafts (MINPO), for the “Entrepreneurial impulse” program, Measure B: “Enhancing business competitiveness of entrepreneurs and craftsmen”, under category B3 “Encouraging innovative entrepreneurship”.

The aim of the WAMSTER-2 project is to adapt the form factor of the portable STER PMU device into an embedded, rail-mounted multifunctional device for permanent installation under the working title SyncPQ. The device in development will support synchronized measurements (PMU), power quality measurements (PQ), remote telemetry (RTU), disturbance fault recording (DFR), with configurable digital inputs and outputs, while still allowing seamless integration with the existing WAMSTER system, third-party PDCs and SCADA systems, and supporting a variety of protocols over different communication channels (GPRS/UMTS, Ethernet, RS232/485).

As a part of the UMEME 24/7 project,
six STER PMU devices were successfully installed in Kenya for our
German client Energynautics GmbH.
The objective of the UMEME 24/7 project is to develop and test solutions that will improve power supply and stability for consumers in Kenya.
The devices were installed with ease and are already measuring data, with preliminary analysis already showing frequent instabilities in their power grid.

Per customer’s request, we enabled automatic daily data exports of Kenya’s PMU measurements to the client’s FTP server,
allowing them to use their own custom tools for data aggregation and analysis.

The white paper covers key technology details behind the WAMSTER Event triggering functionality, and describes some typical use cases for configuring and analyzing events:

• Event triggering introduction: details behind the triggering system, its internals and its limitations;
• Defining processing rules: choosing quantities, preprocessing rules and filters, and chaining them to get various system indicators;
• Configuring triggers: defining relative or absolute comparisons, processing and thresholds for event triggering;
• Analyzing event details: examining measurement trends related to triggered events and exporting data around the event for detailed offline analysis.

Studio Elektronike Rijeka is attending the NASPI group meeting in Denver, CO on June 5th and 6th 2012.
Our company will be presenting the
WAMSTER system and
STER PMU devices at the vendor show.

Denver Task Group meeting is an opportunity to meet with existing and future potential clients and share our experiences in the past two years of WAMSTER
operation. We will provide printed WAMSTER whitepapers and flyers with WAMSTER information, which are available for
download at www.wamster.net.

Flyer for this event contains recent WAMSTER use cases and is available for
download here.
Please contact us if you need any other information regarding our products, or would like to arrange a meeting in Denver.

The white paper covers key technology details behind the WAMSTER system:

• STER PMU, a lightweight, portable, IEEE C37.118 compliant PMU:
  • deployment and configuration of PMU devices is drastically simplified;
  • using a GPRS connection instead of wired Ethernet links removes the need for a dedicated networking infrastructure;
  • rechargeable battery backup keeps the device and the modem online during blackouts;
  • removable SD flash memory keeps up to 4 months of full-resolution data locally, on the PMU device.
• WAMSTER, a reliable synchrophasor concentrator server with data storage as a service:
  • optimized communication protocol adapts dynamically to low-signal mobile network conditions;
  • web application for online data analysis, automatic event triggering and reporting, with data export to customizable formats;
  • data access from any web-enabled device, with full remote PMU setup and management capabilities;
  • easy interoperability with existing systems.
