6kV Box-Type Substation for Energy Storage Integration

This document outlines the general technical specifications for 6kV box-type substations used in energy storage project converter box power station integration. It covers project introduction, including an energy storage configuration of 2MW power and 4MWH capacity for peak shaving and valley filling, with two daily charge-discharge cycles and energy efficiency ≥90%. The system also reduces maximum demand by monitoring load and discharging when limits are exceeded. General principles specify bidder qualifications, compliance with standards, and the need for deviation tables. Technical requirements address box structure, container power station performance, and key equipment like converters and transformers, including performance indicators. Other sections cover testing, technical services, and factory inspection. The document serves as a bidding and contract reference, emphasizing adherence to higher standards and detailed technical parameters for reliable energy storage integration.
