On December 29, 2021, Qinghai Delingha (Tuosu) 750kV power transmission and transformation project, for which CYGSUNRI undertook the integration of secondary equipment, was officially put into operation. The commissioning of the project will further improve the power distribution reliability and power quality of the power grid of the Haixi region, and promote the scale development and transmission of new energy in this area.
As the secondary equipment integrator of the substation, CYGSUNRI has provided monitoring systems with various functions, safe and stable protection devices, main transformer online monitoring devices and intelligent terminals. Since the construction of Delingha (Tuosu) 750kV substation started, CYGSUNRI has carefully organized the personnel inside and outside the factory, rationally arranged the production, joint debugging and on-site debugging, and coordinated and solved the practical problems in the project construction process at the first time. From equipment delivery to commissioning, the engineering service personnel has been staying in the substation site to respond to the project requirements, providing all-round support and solid guarantee for the project commissioning.
During the National Day of 2021, due to the COVID-19 epidemic, close-off management was implemented in the whole substation. The project site is located in the Gobi Desert area, with complex topographical and geological environment, inconvenient communication and traffic, and harsh climate environment. CYGSUNRI actively responded to the epidemic prevention and control work, fully coordinated the delivery of materials and other matters, effectively solved the difficult problem of material arrival, and successfully guaranteed the progress of the project. After the equipment arrived at the site, the engineering service personnel of CYGSUNRI were stationed at the site for debugging, and took the initiative to work overtime in the outdoor temperature of -5℃, overcoming many difficulties. Finally, the installation, debugging and acceptance were successfully completed within 4 months, and all the equipment was put into operation with zero defects.
With the smooth power transmission of this "new green power channel in the Gobi desert", green power in Haixi region of Qinghai will be continuously sent to distant places. CYGSUNRI will continue to engage in this field and move forward, maintain our professional technical ability and high-quality service quality as always, and strive to promote safer and more convenient energy utilization.
