TELUS AND OSM RECLOSERS PROVIDE SMART GRID SOLUTION

The Combination of NOJA Power’s OSM Smart Reclosers and TELUS Software are ideal building blocks for smart grid solutions. TELUS is a software package that can be used to control, monitor and provide engineering access to a standalone system or in conjunction with an existing SCADA communication system. The combination of TELUS and Smart Reclosers provides extra visibility and control to the power grid distribution network.

TELUS Monitoring and Controling Large Population of OSM Smart Reclosers Remotely

NOJA Power’s OSM Reclosers are shipped with the TELUS software package. The TELUS software package allows engineers to remotely analyse fault data configuration settings, accessing detailed data such as fault profiles and remotely changing protections settings. These abilities can be used to provide in depth remote monitoring and control of the OSM smart reclosers.

A key advantage of the TELUS software package is the ability to provide enhancement access to Smart OSM reclosers using the same communication channel as the SCADA system. This reduces setup time and cost of extra configuration. Alternatively TELUS can be used where a SCADA system is not available to provide remote control, configuration and data collection.

TELUS User Interface

The TELUS software and the Smart OSM automatic recloser both use the DNP3 communication protocol. The protocol has an object-base application layer. This gives TELUS and the smart reclosers the ability to support poll-response, polled report-by-exception, unsolicited responses, peer-to-peer operating modes and the ability to communicate with multiple masters. These capabilities provide extra flexible options for building the Smart Grid system.

The DNP3 communication protocol has a strong community base and is used by multiple vendor devices and SCADA systems. This means no integration translation is required, reducing integration costs and reducing maintenance and training costs.

NOJA Power’s OSM reclosers also provide other protocols such as Modbus and IEC communication protocols. This allows more integration flexibility, enabling the reclosers to communicate with a variety of SCADA Networks and smart devices.

The combination of NOJA Power OSM smart reclosers and the TELUS software brings continuous reliability and smart solutions to the current power grid system. This extra power to control and monitor the grid, decreases live line maintenance costs and increases the overall health and performance of the power grid system, benefiting both the electrical utility and the general public.

NOJA POWER AUTO RECLOSER OPERATING SMART GRIDS BELOW FREEZING

Europe is experiencing one of the coldest winters in 15 years according to the UK Met Office (Meteorological Office). Despite the harsh weather condition, NOJA Power OSM reclosers are operating reliably throughout the region.

NOJA Power OSM27 Smart Automatic Recloser Operating Under Harsh Weather Conditions

Across Europe, temperatures have dropped well below freezing with one of the lowest temperatures ever recorded at -22.3C. The Met Office said the temperatures are set to stay below zero degrees with a risk of further snow.

During winter, NOJA Power reclosers are used to secure and protect power networks. Remote monitoring, control and intelligent self healing capabilities of these reclosers allow power networks to operate efficiently and reliably under extreme weather conditions. 

Heavy snow and road blocks can mean decreased accessibility to remote power distribution equipment; NOJA Power’s smart reclosers restore power after faults occur automatically where possible. They can also automatically isolate a fault to protect the rest of the network.

NOJA Power’s automated intelligent reclosers are rated for use in environmental extremes from -40°C to +55°C ambient temperature. They are used in a wide range of locations and scenarios from thunder storms, lightning strikes in tropics to snow storm and blitzes in cold environments.

Installing several smart reclosers in series to sectionalise faulted sections of line during heavy snow storms helps utilities increase reliability.

Remote control and monitoring using GSM modems or VHF/UHF radio systems gives access to the full function of the auto reclosers. The Recloser supports DNP3, Modbus and IEC communications protocols for flexible SCADA integration.

The benefits to both business and the general public are significant. Installing NOJA Power smart automated reclosers has considerably increased reliability. Reduced line crew deployment costs and maintenance costs have resulted; power outages have decreased which helps utilities and the local community to keep heaters going during harsh, cold weather conditions.
