Under the construction of the new power system, green energy such as photovoltaic and wind power is accelerating to become the main body of the energy structure. However, the volatility, intermittency of new energy, and the harsh outdoor environment (high and low temperature, wind and sand, humidity, salt spray) pose severe challenges to the power supply system of power stations. How to ensure the stable power supply of key loads such as booster station and station protection, control, and communication is the core proposition of new energy power stations to achieve safe operation and stable income.
Huiye Da has been deeply involved in the field of industrial power supply for 30 years, providing core power supply guarantees covering AC and DC power supply systems and UPS power systems for new energy power stations, and helping new energy stations cope with extreme working conditions and ensuring stable income throughout the life cycle with highly reliable redundancy architecture and intelligent operation and maintenance capabilities.
| Pain point needs | System type | System introduction | System features: | Customer value |
• Photovoltaic and wind power plants are mostly located in remote areas, with harsh environments (high and low temperatures, wind and sand, humidity), and poor adaptability of traditional power supply equipment • The power grid fluctuates frequently and requires extremely high power supply reliability •There are few operation and maintenance personnel, and the equipment needs to have remote monitoring and unattended capabilities. | AC and DC power supply systems | New energy power system solution Highly reliable and redundant power supply solution designed for new energy stations (photovoltaic/wind/hydropower). Adopting the complete dual configuration of "two independent intelligent charging modules + two high-performance battery packs", seamless backup and load balancing are achieved through intelligent bus switching logic to ensure that the system can continue to provide uninterrupted power for core loads such as protection, control, and communication when any single charging module or battery pack fails. | • High frequency and high efficiency, dense power • Module redundancy, online maintenance • Panoramic view, intelligent alarm • Global parameters, remote control • Open protocol for seamless access • Plug and play for easy maintenance | • Improve power supply reliability and eliminate single points of failure • Unified monitoring simplifies operation and maintenance to meet the unattended needs of intelligent substations • Optimize life cycle cost (TCO) • Support intelligent upgrading and sustainable development |
•The monitoring system, communication system, and automation device of the new energy power station have high requirements for the purity of power supply, and fluctuations in the power grid may lead to equipment restart or data loss • Remote areas are inconvenient to maintain, and the equipment needs to have remote monitoring and fault self-diagnosis capabilities | UPS power system | UPS power supply system is a dual-conversion online uninterruptible power supply system with pure sine wave output, which provides power supply equipment for important loads without grid interference, voltage regulation, and temperature frequency. When the mains power is lost, the UPS outputs the battery energy inverter to the load to achieve uninterrupted output. All power converters (e.g. triacs, IGBT inverters, etc.) and system components (e.g. bypass and static switching of inverters) used in this series of UPS are controlled by advanced DSPs (Digital Signal Processors). The high speed and precise control performance of the DSP greatly improve the control accuracy of the UPS, further enhance the reliability, and achieve stable, clean and uninterrupted power output. At the same time, it also provides a variety of communication solutions and a friendly human-machine interface, which is convenient for users to design and monitor the machine. | • Online dual-conversion DSP technology • Independent air duct heat dissipation design to ensure uniform heat dissipation of the whole machine • Automatic bypass and external manual bypass design to ensure uninterrupted power supply for repairs • Redundant design of power strips to ensure a safer system • Pure sine wave output, high voltage accuracy, low total harmonic distortion • Rich communication interfaces, equipped with RS485, RS232, RJ45 and other interfaces | • Ensure the continuous operation of core systems such as signals and communications, and eliminate operation interruptions caused by power supply problems • Easy operation and maintenance, reducing fault repair time. • High efficiency and energy saving, directly reduce electricity bills; Intelligent battery management extends battery life and reduces replacement costs • Transform UPS from a "black box" device to a digital asset for transparent management |
