2 Modular Secondary Combined Equipment and Its Advantages
2.1 Basic Definition
Masana'antar combined secondary na prefabricated cabin sun hada da prefabricated cabin, secondary equipment cabinets, da kuma secondary equipment. Duk aikin masana'antar biyu ana takarda a factory, kuma wiring bayan cabinets ana kammala a factory. Ana karkashin zuwa nan kamar yadda, don inganta connection with primary equipment da kuma civil engineering. Yanzu, modular combination ana karkashin zuwa nan a cikin characteristics na system na biyu da kuma primary objects it serves.
2.2 Core Advantages
Masana'antar modular secondary combined yana inganta implementation of "standardized design, factory-based processing, and prefabricated construction". Components na structures suna takarda a factory, yana ba da taimaki a cikin plug-and-play of primary and secondary equipment, kuma yana bayar da intelligent substation na full prefabrication and assembly. Abubuwan da suka fi shi muhimmanci sun hada da:
Haifatar Kasa da Tsaunukan Al'amuran: Ta haka haka, tana haifar da building area da kuma yawan kasa, tana rage yawan installation links, kuma tana haifar da yawan tsaunukan al'amuran;
Efficient Integration: Masana'antar biyu ana takarda, installed, da kuma wired a factory, integrating functions, improving the integration degree, saving equipment resources, reducing on-site workload, and meeting the requirements of "resource-saving";
Optimized Commissioning: Innovates the "factory joint commissioning + on-site commissioning" mode. The factory simulates the operation scenario, completes the solidification of SCD files (such as the whole-station five-prevention logic and signal point table naming), and only needs to conduct transmission verification with primary equipment on-site;
Simplified Design: After factory joint commissioning, a complete virtual terminal point table is generated, which can be attached to the design documents as needed to meet the requirements of dispatching in various regions;
Cost Reduction: The secondary equipment is arranged in the distribution interval on-site, shortening the length of secondary optical cables and cables, saving materials, and reducing costs
Construction Period Compression: Changes the serial construction to parallel construction, saving more than 60% of the on-site commissioning cycle.
3 Current Status of the Secondary System of Intelligent Substations
A cikin current construction of intelligent substations, the on-site installation and commissioning of secondary equipment have obvious problems:
Process Constraints: The installation of secondary cabinets depends on the completion of civil engineering, and the optical/cable wiring of the secondary system can only be carried out after the cabinets are in place. As a result, the commissioning of the secondary system is restricted by the construction progress of civil engineering and primary equipment, prolonging the cycle;
Low Efficiency: There are many commissioning projects and complex technologies. The after-sales personnel of the manufacturer need to be stationed on-site, which is difficult to meet the needs of large-scale promotion, and the efficiency is limited;
Environmental Hazards: There is a lot of dust on-site, and the optical ports of secondary equipment are not well protected, affecting the performance and service life of the devices;
Increased Land Occupation: Conventional secondary equipment requires an independent control room, occupying land resources, increasing civil engineering volume, and is not conducive to land conservation.
4 Conclusion
Compared with conventional substations, the prefabricated cabin-type combined secondary equipment has prominent advantages:
Through technological innovation, the prefabricated cabin-type intelligent substation meets the development needs of the power grid, and has remarkable effects in cost reduction, efficiency improvement, and green construction, and has extensive promotion value.
