China co-authored with the Internet Liaoning: the world's first power-to-light network model was unveiled

News from IT House on 5 June, yesterday, Uhua, NNE Liaoning Electricity, Inc., announced that the first power-to-light network model site in the world, created by both sides, had been officially unveiled at the 2026 Energy Network Conference on Innovative Applications of Communication, held in Dalian.

The template covered the main network, fgOTN, high-separation grids PON, full-light intelligence transformer stations and low-pressure HPLC, four core applications, resulting in a replicable, new-style power system communications target network complete programme, which provides a “China model” for upgrading the global power network.

As the “master network artery” in the entire communications architecture, fgOTN technology has led to mature commercialization. The IT House query was informed that, as early as 2023, the national net Liaoning power had completed the first global set of equipment-to-grid tests in support of the fgOTN standard at 220 kV, and the full scene validation covering 8 of the 27 test items the following year. By March 2025, the company had further deployed and put into operation equipment in support of the fgOTN and SDH dual-technology systems at Hanton, Tiger Stone Station and East kiln substations. After more than a year of uninterrupted physical operation, operational indicators have stabilized to meet the technical requirements of the power system.

The flexible access capacity of the fgOTN technology set SDH and the large bandwidth advantage of the OTN are capable of carrying both 2M small particle relay protection and 1,000M large particle integrated data. Operational security through physical isolation has led to the establishment of the National Net Liaoning Power Network as the world ' s first fully-fledged commercial fgOTN provincial power grid enterprise and has been deeply involved in the development of international standards for fgOTN.

On the side of the distribution grid, the introduction of high-segregation PON technology has changed the traditional idea of separate networks. In the past, the automation of distribution and video surveillance required the establishment of independent communication networks, which resulted in low investment utilization and complex post-management. Through a very simple and integrated structure, PON has achieved a single network that carries both control and non-control types of business without interference. MA5621E, an autonomous innovation device used in the programme, supports EPON and GPON to adapt to the two models, with -40°C to 70°C wide-temperature capacity, 6kV mine-protected level, illegal access and 50 millisecond class telecommunication double-link conversion capability. In conjunction with the “one map of the distribution network” management platform, it will be possible to complete a panorama of cables, equipment and operations, as well as an intelligent analysis and positioning of failures. This portfolio has become the mainstream option for new and expanded power distribution networks.

For the end-end scene of the station, the All-Ray-Intelligence Transformer solution is based on end-to-end light technology and is designed to achieve the objectives of “no manual monitoring, no manual inspection, no manual copying, no manual analysis”. The White Light and Temperature Cloud Station on board the program supports prepositioning and one-key correction, which increases the efficiency of inspection assignments by 75%. IVS1900 provides up to 420TOPS, supports the parallel operation of six power survey algorithms and rapidly locates events within the electric park using smart text search. At the same time, the optical perimeter protection technique can achieve a security effect of almost “zero underreporting, under-reporting”, with 7x24 hours of unsupervised patrols allowing transport personnel to be released from the risk of operating in high-pressure areas and facilitating the upgrading of transformer stations in the direction of low-capacity, unmanned operations, intelligence analysis and security.

The HPLC (high-speed power line carrying) technology, which moves deep into low-pressure areas, plays the role of a “end-of-neumatic” power communication, significantly enhancing the overall performance of the electro-information-gathering system. HPLC is able to collect and control photovoltaic energy in real time in a distributed photovoltaic large-scale access scenario, effectively preventing reverse power overload and achieving photovoltaic crowd control. Its collection success rate reached 99.9 per cent, significantly reducing the redundancies of grass-roots personnel. In addition, in conjunction with AI analysis, load data collected in real time through HPLC can automatically generate photo-recharging regulation strategies in the energy scene of the station, mitigate the overload risk of the voltage transformer and guarantee the safe and stable operation of low-pressure table areas.
