重合闸监控

IP over satellite provides the most reliable and cost-effective option to remotely monitor and control centralized reclosers in areas where terrestrial connectivity is unreliable. Viasat’s IoT Pro service is used on tens of thousands of reclosers around the world and has been trusted as the industry standard by electricity providers for over ten years. 

The service operates on Viasat's L-band network. Created for government and emergency applications, 它是最可靠的卫星, 最多99个.9% network availability in practically any continental location, even in adverse weather conditions such as heavy rain. 

所面临的挑战

To meet the surging demand of a fast-changing world, energy and a dependable electrical supply have never been more critical. Electrical utility network operators are under increasing pressure to uphold exceptional levels of service, quality, 和可用性, with failure to meet government-mandated standards leading to substantial fines. 

提高服务可靠性, distribution network operators (DNOs) are adopting smart grids, with critical components managed by supervisory control and data acquisition (SCADA) networks. Circuit reclosers play a key role by sensing and interrupting current on a grid segment during faults. While these devices can trip and reset independently, unconnected reclosers may enter a lockout state once tripped, requiring an engineer response to reset them. Centralized SCADA monitoring and control not only eliminates this risk but also enhances data access in a control room. 

For a centralized reclosers approach, secure and reliable connectivity is critical. With many DNOs managing grids that span across wide territories, 经常穿越偏远地区, cellular or other terrestrial options cannot always be relied upon. 

Our solution

Viasat的卫星IP服务, delivered over our highly reliable L-band network, adeptly meet the high levels of network availability required for connecting reclosers, 作为主连接或备份连接. 为安全可靠的连接24/7, DNOs can easily connect their reclosers to Viasat’s IP connectivity services by using the Hughes 9502 BGAN or the Cobham 540 BGAN, which combine cellular with satellite fallback in one unit. 

DNOs incorporating centralized reclosers into their networks should prioritize the reliability and resilience of their connectivity infrastructure. While terrestrial services are likely the main communication backbone, they may be inadequate in remote areas or during adverse weather. Viasat卫星服务利用 IoT Pro terminals over our global L-band network will help DNOs achieve the required service continuity, 即使在恶劣的天气条件下. 

Benefits

• 更容易管理: Enhanced operations management, including monitoring and control from SCADA control room.
• Reduces risk and cost of sending field engineers to reset tripped reclosers:
  • Eliminates the need for field engineer allocation and significantly lowers the risks associated with this type of activity, including working with high-power electrical components, 在高空操作, which often requires a minimum of two engineers, 前往可能偏远的地点.
  • No time is lost on dispatching workforce to reset reclosers as this can be done remotely, immediately.
• 远程控制: Enables utilities operations to remotely disable the automatic recloser function in dry seasons to avoid starting wildfires.
• 尽量减少错误: Enables DNOs to identify and limit the spread of faults, mitigating risk of serious operational impacts.

Features

• 轻松集成Viasat很小, low-power IoT Pro terminal easily integrates with reclosers to provide reliable, 均匀覆盖, while its standard IP protocols allow for seamless and secure integration as part of an existing or expanding grid.
• 集中控制: Centralized management capability at a low cost no matter how remote the location, provides power companies with remote control and recovery services for the grid.
• 减少工地参观次数: Exceptional reliability of both our L-band connectivity service and the hardware helps users avoid site visits or the need to change hardware in the field for decades at a time.
• 简单的维护:  IoT Pro offers remote management capabilities, including remote firmware updates and self-healing functions.
