The shift to renewable energy brings new engineering challenges, and power distribution equipment must actually be uniquely adapted, with rugged, flexible designs suited to diverse renewable generation systems. Whether it is solar farms spanning deserts, wind turbines on mountain ridges, or energy storage systems in varied locations, electrical transformer actually plays pivotal role in converting as well as transmitting power reliably under adverse conditions. Traditional power generation infrastructure, more conventional power plants are usually located relatively close to load centers, to actually meet demands from load, whereas renewable energy plants like wind and solar farms are remote from main load centers.
This makes selection of suitable and highly reliable equipment vital, in such case electrical transformer is critical component between renewable energy source and power grid. The Jiangsu Ryan Electric Co., Ltd. has extensive experience, in producing robust, reliable and efficient, power transformer for all kind of renewable applications globally.
Stepping Up Voltage for Long-Distance Transmission
The efficient transmission of power over long distances has always been significant design criterion for all kind of electrical projects. Solar and wind forms are usually designed to capture solar or wind energy when it is abundantly available in some location. Usually it is far from an urban centers and populated areas, electricity generated must then be transmitted. The electrical transformer increases level of generated power (which usually is in low-medium voltage range between 3.3 kV to 35 kV) to higher transmission voltage level (up to 132 kV) which considerably reduces electrical power loss during long distance transmission.
Ryan’s power and distribution transformers are designed to fulfill these requirements with high reliability through use of robust insulation systems and efficient cooling structures to operate continuously at high voltage rating, The power transformers' capacities are manufactured up to 10 MVA, with rigorous tests being performed in CNAS-accredited 35 kV and 110 kV laboratories to transmit renewable energy with minimized power loss.
Withstanding Extreme Environmental Conditions
Renewable energy systems are usually placed in an undesirable environment where conditions are difficult to endure, solar farm which is located in Middle East country may experience ambient air temperature at more than 50°C, strong exposure of sun rays and fine sand. A wind farm is exposed to salt spray, high level humidity and high storm, as well as mountain top wind turbines that might experience ice, snow and lightning strike impact during severe storms. All of these demanding situations require extremely robust electrical transformer units designed specifically for such extremities. The Ryan electrical transformer with oil immersed design has advanced cooling mechanisms and conservator structure which maintain dielectric integrity even under continuous high temperature environment. Dry type cast resin transformers are capable of resisting relatively higher degree of humidity, dust and other environmental risks in tropical regions. All of these electrical transformers units from Ryan have received approval according to IEEE standards, UL standards, CE standards, ASTA standards and also are customizable for tropical, deserts or coastal locations to perform at optimal level for long time and minimize any unscheduled outage.
Managing Bidirectional Power Flow in Energy Storage Applications
It has become very important for every power grid to achieve grid stabilization and stability by incorporating energy storage systems in grid. These systems need transformers with bi-directional flow capabilities in both ways, either in and out to charge and discharge when required. Ryan transformers can perform bidirectional power flow with reliable mechanical structure and sufficient tap changing capacity which are essential factors for dynamic power transmission without performance degradation for energy storage applications. The R&D department of Ryan, with high experience in development of customized electrical transformers can provide all necessary technical assistance for utility scale energy storage projects by matching each specific voltage level and operation duty of these storage systems in term of power requirement and transformer operation range. The electrical transformers are approved and comply with most widely use bidirectional standard, IEC and IEEE standards.
Delivering Reliability Through Rigorous Testing and Global Standards
Energy generation projects which often require huge capital cost to be invested are always required to achieve strict performance parameters in power purchase agreement, so it is really unacceptable to face such interruption resulting from electrical transformer failure causing an enforced outage. The Ryan Company’s electrical transformer has always focused on aspect of high quality and strict tests, where every electrical transformer unit would have to undergo various tests like routine, type & special test for lightning impulse, temperature rise and short circuit withstand tests in dedicated test rooms by highly skilled technician. All electrical transformers are tested and have verification and certificates from UL, CSA, CE, DEKRA, ASTA, and comply with most world common used electrical standards such as ISO, IEC, IEEE, GB standards to meet financial and insurer needs for renewable project. The successful installation references such as Microsoft and many national grid operators provide an assured reliability on Ryan's electrical transformers for sustainable and longterm operational performance in challenging renewable energy landscape.
