1.Background

The  HQL Power Plant is mainly engaged in thermal power generation, comprehensive utilization of fly ash and research and development of thermal power generation technology. 


It is one of the main power points of the national“West-to-East Power Transmission” project.


In Mar 2018 HQL Power Plant required IFLY to build up a stable private LTE network aiming to:

①  Rapid Emergency Response 

②  Manage High-risk Work

③  Computer Inspection

④  Build A Smart Power Plant

⑤  Build A Secure & Reliable Private Network

   

2.Challenges


①  Unreliable Communication System Makes Blackout Worse


Unable to detect the accidents immediately                →  Require a reliable communication Network

Unable to isolate the accidents immediately                →  Require a real-time video monitoring for surveillance

Unable to dispatch the first responders immediately   →  Require a trunking system for quick response


②  Hard to Communicate in Remote Areas


It is too far or too expensive to lay fiber in remote areas →  Require communication in remote areas

Natural disaster may damage fibers                                  →  Require recovering communication rapidly

Existing public network is unreliable and unsafe              →  Require providing more protections for communication network


③  Hard to Provide Safety Managements and Accidents Location


Requirement for unattended management mode of electric power plant → Require full-coverage, high-definition and real-time surveillance

Requirement for accidents location & recover in electric power plant → Require reliable communication under electromagnetic interference

Requirements for reliable monitoring in electric power plant → Require centralized management, visualization monitoring & dispatching


3.Solution

According to the HQL Power Plant's actual condition, IFLY made a solution: Distributed base station combines with mobile base station to cover the whole factory area.

Emergency Command Solution

Features of the Solution


1.8G Lte outdoor RRU is supplemented by an indoor RU covering 60%~80% of the plant area. The 400M Lte portable base station is used as a temporary coverage for blind spot coverage.


● Combine fixed and mobile to reduce costs.

● Take advantage of the mobility of portable base stations to cover any production area within the plant.

● Take advantage of the strong 400MHz carrier diffraction capability to form a good coverage of dense metal pipes.

● Conducive to the step-by-step network implementation. Portable base stations can be quickly deployed with 15minutes.

● Provide:

UP:9Mb/ DOWN: 100Mb

UP: 19Mb/DOWN: 50Mb

UP: 28Mb/DOWN: 40Mb


Three network bandwidth modes can be configured according to the actual use of the power plant.

6.Conclusion

According to this test, 80% of the production area's video transmission quality meets the needs of HQL Power Plant


Portable base station is used for coverage blind spots and works well. In this way no blind zone coverage in the production area can be achieved.
