The collection features typical success cases of the company across multiple regions and industries worldwide, covering three core business areas: including a commercial and industrial energy storage system project at a factory in Europe (achieving a 30% reduction in electricity costs), an EV charging network project for a community in North America (compatible with the NACS standard, meeting the charging needs of 500+ parking spaces), and a smart grid optimization project in a region of Asia-Pacific (reducing fault recovery time by 80% through recloser controllers and distribution automation systems), among others.
Successful Case of Renovation and Intelligent Optimization of 10-40.5KV Vacuum Circuit Breaker in Bangladesh
Project Background: Focus on Bangladesh Power Grid Pain Points and Explore Upgrade Paths Together
In recent years, with the rapid economic development of Bangladesh, the demand for electricity has been continuously rising, and the upgrading and transformation of power grid infrastructure have become key initiatives to support the country's energy security and economic growth. In in-depth communications with the local core power supply company, we found that the 10-40.5KV vacuum circuit breakers installed on its overhead lines generally have serious product aging problems, and the overall intelligence level of the lines is relatively low, which can no longer meet the needs of safe and stable operation and efficient operation and maintenance of the modern power grid.
Specifically, the aging vacuum circuit breakers not only have a high failure rate, which increases the on-site operation intensity and safety risks of operation and maintenance personnel, but also have defects such as single protection functions and slow action response, which are likely to expand the fault scope; the lack of intelligence makes it impossible for the power supply company to realize real-time monitoring, remote control and precise fault location of the line operation status, relying heavily on manual inspection with low operation and maintenance efficiency. This further exacerbates the instability of regional power supply and restricts the guarantee capacity of local industrial production and residential electricity consumption.
Solution: Customized Recloser Controller to Solve Dual Problems
As a professional manufacturer of vacuum circuit breaker controllers and recloser controllers, based on in-depth research on the operating environment of Bangladesh's power grid and a profound understanding of international power industry standards, we have tailored a 10-40.5KV vacuum circuit breaker transformation and intelligence optimization solution centered on the latest recloser controller for the power supply company, accurately solving its dual problems of equipment aging and lack of intelligence.
The recloser controller provided by us has a full range of precise protection functions, including core function modules such as current three-stage protection, phase fast-slow curve protection, zero-sequence current three-stage protection, zero-sequence fast-slow curve protection, and sensitive ground protection. It can quickly respond and act accurately to various fault scenarios (such as overload, short circuit, ground fault, etc.) during the operation of overhead lines, effectively cut off the fault line, minimize the fault impact scope, and ensure the stable operation of the rest of the power grid.
In terms of intelligent communication, the controller is fully compatible with a number of international mainstream communication protocols, including IEC60870-101 balanced/unbalanced, IEC60870-104, MODBUS RTU, MODBUS TCP/IP, DNP3.0, etc. . Among them, the IEC60870-104 protocol, as the core standard for telecontrol communication in power system automation, can realize the seamless connection between the controller and the power system background SCADA system, helping the power supply company build a remote monitoring and dispatching system covering all overhead lines.
Project Results: Comprehensively Improve Power Grid Performance and Gain High Customer Recognition
After the implementation of the transformation and intelligence optimization solution, significant application value has been quickly demonstrated, winning high praise from the Bangladesh power supply company. By replacing our customized recloser controller, the safety performance of the aging vacuum circuit breakers has been fundamentally improved, the failure rate has been greatly reduced, the equipment operation and maintenance cycle has been significantly extended, and the comprehensive cost of equipment replacement and operation and maintenance has been effectively reduced.
More importantly, the intelligence level of the line has achieved a leapfrog upgrade. Through the SCADA background system, the power supply company can real-time collect core data such as line current, voltage, and equipment status, realize remote control, remote adjustment and remote signaling of the recloser, completely getting rid of excessive reliance on manual inspection, and the operation and maintenance efficiency has been improved by more than 60%. At the same time, with the help of the controller's precise fault location function, operation and maintenance personnel can quickly lock the fault point, greatly shortening the fault handling time, significantly enhancing the regional power supply reliability, and providing a solid energy guarantee for local industrial economic development and residential electricity consumption.
The successful implementation of this project not only demonstrates the technical competitiveness of our products in the international power market, but also lays a solid foundation for Sino-Bangladesh cooperation in the power field, providing a replicable and promotable intelligent solution for the upgrading and transformation of Bangladesh's power grid.
