The inspiration comes from! Industry-leading pumped storage capacity layout
In order to create more super power "granaries" and better serve the "dual carbon" goal, Dongfang Electric has formulated and released a plan to increase pumped storage capacity during the "14th Five-Year Plan" period.
In terms of digital empowerment, based on the results of digital design, Dongfang Electric has tailored different transformations according to the operation characteristics of each production workshop, in combination with the “14th Five-Year Plan” pumped storage capacity improvement, core manufacturing planning, process layout adjustment and production practice. The plan is to promote the construction of digital workshops through the overall linkage of points and areas. At present, Dongfang Electric has built a large-scale digital workshop for heavy-duty clean energy equipment manufacturing, the world's first green "unmanned workshop" for stator punching, and a "high-quality + green" digital workshop for magnetic poles. Efficient output.
In terms of core manufacturing, Dongfang Electric has scientifically and meticulously defined the 8 parts, 27 components and 436 processes of the pumped storage unit, forming the normative and guidance for planning in terms of design process, supply chain construction and quality inspection planning. This document effectively ensures the unity, integrity and forward-looking of each plan.
In terms of process layout, Dongfang Electric focuses on the improvement of pumped storage capacity, industrial development and digital workshop construction, and based on the optimal process flow, it adjusts the process layout, adjusts the process layout, supplements the operating area, and increases the pumped storage on the original basis. Product work area.
