Project Background
Guoneng Group is facing the challenge of integrating heterogeneous data from multiple sources in thedistributed PV power stationgroup of "Data Acquisition IoT Project Sites 1 to 19", and needs to build a closed-loop system covering equipment monitoring, cross domain transmission, and intelligent analysis. With ten years of technological accumulation in the field of energy IoT, our company has built the industry's first intelligent platform that supports the integration of data from third level enterprises.
Core technology breakthrough
1. Protocolis fully compatible with edge collection terminals
- adaptationGudewei inverter series（XSG3/DNSG3/MSG3/SDTG3）， ByMODBUS-RTU Reverse Analysis EngineRealize 5-minute precision collection
- Innovative DesignEdge Computing Preprocessing moduleThe data compression rate reaches 60%, effectively reducing bandwidth pressure (measured APN dedicated line traffic reduced by 47%)
2. Transmission topology of five level linkage
- Original creationDynamic Link Optimization AlgorithmIn weak signal areas such as 3/12 at the project site, a delay of ≤ 5 seconds is still achieved
- ByBreakpoint fingerprint continuation technologyEnsure 72 hours of offline caching and zero packet loss (verified with 10000 interruptions in the testing environment)
3. AI driven data center
- Based onPrivacy Computing Framework for Federated LearningRealize the integration of water and electricity/PV data security
- DevelopmentEnergy portrait engineAutomatically generate daily/monthly/year-on-year analysis (covering 98% of business indicators)
Realize the effect
| indicator | Contract requirements | Actual delivery |
|---|---|---|
| Data latency | ≤ 5 seconds | 1.2 seconds |
| Interface concurrency capability | QPS2000 | QPS3150 |
| Fault recovery time | ≤ 5 minutes | 83 seconds |
| Data error rate | ≤2% | 0.7% |
Customer Value
- O&M Efficiency improvement
▶ Remote fault diagnosis response speeds up by 60%, reducing on-site inspection frequency
▶ The maintenance cost of high-altitude stations such as 7/15 in the project site has decreased by 35% - Decision upgrade
▶ Constructing a solar water complementary power generation model, increasing the power generation of the project site by 12% in 9 years
▶ Unified view management for 19 sites, increasing resource allocation efficiency by three times - Safety compliance
▶ Passed Level 3 Certification of Waiting for Insurance 2.0
▶ Compliant with 22 standards including IEC CIM/GJB 12325
Technical radiation application
This scheme has been validated for replicability in multiple scenarios:
- Mining PV+energy storage linkage(A mining area in Xinjiang)
- Fishery light complementary IoT system(Jiangsu Aquatic Products Base)
- Cross border multi country data exchange(Southeast Asia 500MW project)
