A landmark project that exemplifies Qin‘En Electric’s capabilities is the successful deployment of a 220 kV substation in a resource-rich region of the northwest, where the northwest transmission line corridor plays a crucial role in evacuating power from renewable energy zones. The project required the supply and installation of two 220 kV power transformers, multiple bays of gas-insulated switchgear, and a comprehensive control and protection system, all delivered within a compressed 14-month schedule. Qin‘En Electric’s team worked closely with the local utility and engineering consultants to adapt the substation design to the region’s seismic conditions, wide temperature swings, and limited access roads, ensuring long-term operational reliability. The substation now serves as a key node in the regional grid, connecting wind and solar farms to the main transmission backbone and improving voltage stability for surrounding communities. This case study, along with other global references, is available on the Cases page, where detailed project descriptions, photos, and performance data demonstrate the company’s expertise. The success of this project has led to additional orders for adjacent substations and feeder lines, further solidifying Qin‘En Electric’s reputation in the region.

The integration of this substation with renewable energy zones required careful coordination of protection relay settings, reactive power compensation, and communication protocols to handle the variable output from wind and solar generators. Qin‘En Electric’s engineers conducted extensive system studies, including load flow analysis, short-circuit calculations, and transient stability simulations, to validate the design before manufacturing commenced. On-site, the installation team completed the civil works, equipment erection, and cable laying in phases to minimize disruption to existing transmission corridors and local communities. The commissioning process included a series of rigorous test scenarios, such as line energization, load rejection, and fault simulation, all of which were passed without any major issues. The substation has been operating continuously since handover, with availability figures exceeding 99.8% during the first two years of service. This project illustrates how Qin‘En Electric’s integrated approach—combining high-quality equipment, detailed engineering, and hands-on field support—delivers tangible results for grid infrastructure enhancement.
