Serving spring plowing and spring irrigation with safe and secure electricity, supporting rural industries

Winter is coming and spring is coming, in the greenhouse of Majiagang Strawberry Planting Base, Yiquan Town, Donggang City, Dandong, Liaoning Province, grower Zhao Xiumei Busy with drip irrigation, picking and pruning, the second crop of spring strawberries are being neatly packed into foam boxes one by one and will be sent to all parts of the country within 48 hours. Technicians from the Power Distribution Technology Center of the State Grid Liaoning Electric Power Research Institute and inspection personnel from the Seat Power Supply Station of the State Grid Dandong Power Supply Company are inspecting the switches, leakage protectors, pumping, insulation, lighting and other equipment of the greenhouse, and Help replace aging knife switches, socket switches and other electrical facilities.

Majiagang, Yiquan Town, Donggang City, Dandong, is one of the first northern winter strawberry producing areas in my country, with a history of nearly a hundred years. After years of development, the local area has summarized a set of standardized strawberry cultivation technical regulations, ensuring the yield and quality of strawberries, and making the plump, delicious and juicy Dandong Donggang strawberries a shining city business card.

Spring always comes very late in the Northeast. Spring sowing has not yet begun, but the greenhouse is already full of green, and the fragrance of strawberries and the fragrance of earth hit our faces. Since 2011, open-air strawberries have been gradually phased out, and greenhouses have been built. The strawberry greenhouse simulates the temperature, humidity and light required for strawberry growth, helping strawberries "get rid of jet lag". As the technological level of strawberry planting improves, the electrification and automation equipment in strawberry greenhouses, such as well pumping and drip irrigation, rolling shutter machines, blowers, conveyors, etc., have also increased, and the demand for reliable power is also increasing day by day.

In order to ensure reliable power supply for the Majiagang Strawberry Base, the local power supply station has expanded, upgraded, and transformed the Xudaling line many times. However, some farmers and greenhouses at the end of the line are still often affected by low voltage problems. Troubled. "The winter before last, the rolling shutter machine couldn't start several times when it snowed, so we had to go to the shed and roll it down one roll at a time." Zhao Xiumei said.

State Grid Liaoning Electric Power Research Institute has always regarded helping agriculture and rural areas improve production and living conditions as a key task. In 2022, the institute will conduct simulation calculations on the Xudaling Line through its independently developed low-voltage simulation comprehensive management system and provide operable comprehensive transformation suggestions.

This trip to Dandong is not only a survey of the new reconstruction lines, but also a return visit to the historical governance work. "Thanks to the transformation and management plan of the Institute of Electrical Power Research, we have a follow-up to the transformation and solved the low-voltage problem in one step with the least amount of money." said the relevant technical staff of Dandong Company.

“Last winter’s strawberries were big and sweet, which really made us have a good year. We spent more than 200,000 yuan on building the new greenhouse, and we got our money back this year!” Zhao Xiumei said: "After the renovation at the end of last year, I no longer encountered the problem of rolling shutter machines. I also installed deep well water pumps for each greenhouse. Now it doesn't take long to take care of these sheds every day. Next year I will prepare Build another two acres of greenhouses”

“Berry” has a good life and is protected by electricity! Facing the future, State Grid Liaoning Electric Power Research Institute will continue to focus on the comprehensive management of low voltage in distribution lines and the optimization of reactive power compensation in distribution station areas, and systematically solve the low voltage problem in rural areas on the basis of providing power to every village. Let the majority of farmers use safe electricity and have peace of mind, and provide reliable power technical support to assist rural revitalization and development and serve spring plowing and spring irrigation.
