Wind turbine and photovoltaic inverter only generate low voltage alternating current that cannot be directly transmitted to regional power grids for long distance delivery. Step up transformer converts low voltage power output from power generation equipment into medium and high voltage electric energy, cutting transmission loss during long distance cable delivery. Every single wind power unit and photovoltaic power generation module needs matched step up transformer to complete voltage conversion before grid connection. Without this core transformation equipment, new energy power stations cannot realize large scale clean power outward transmission to supply urban industrial and residential load demands.
New energy power stations operate day and night to maximize clean power output, requiring transformation equipment with ultra low energy loss performance. Step up transformer adopts amorphous alloy silicon steel core and compact short distance winding to reduce eddy current and no load power consumption effectively. Under full load operation all day long, energy loss index stays far below international standard limit, helping new energy project operators lower total electricity loss every year. The energy saving feature greatly improves comprehensive power generation income of wind and photovoltaic projects with long term operation cycles.
Wind farms and large scale photovoltaic power stations are mostly built in open desert plateau and coastal zones with severe natural conditions. Step up transformer supports full sealed outdoor casing with IP54 protection grade, blocking sand dust rainwater and salt mist from invading internal coil components. Special high temperature resistant insulating paint is coated on winding surface to maintain stable insulation performance under long term sunlight exposure. The anti aging structure extends service cycle of step up transformer without frequent on site maintenance in remote new energy bases.
Grid companies set strict voltage fluctuation limits for new energy power station grid connection to protect stability of public power supply network. Step up transformer equips precise voltage adjustment module to stabilize output voltage within tiny error range even when wind speed and sunlight intensity change constantly. Harmonic suppression structure reduces power grid pollution caused by new energy power generation, passing all grid access detection standards of global countries. Project owners do not need to install extra filtering equipment to finish grid filing procedures.
Wind power and photovoltaic projects have differentiated single unit power specifications from small distributed power stations to gigawatt large scale power bases. Step up transformer product line covers complete capacity range matching small distributed photovoltaic modules and large megawatt wind turbine units. Parameter customization service adjusts rated voltage frequency and protection level according to local power grid standards. Unified product series simplifies procurement and spare part inventory management for new energy engineering contractors undertaking multiple overseas projects.
Most modern large scale new energy projects adopt integrated containerized substation layout to shorten construction cycle and reduce land occupation area. Step up transformer adopts optimized compact internal structure that can be installed inside standard container power distribution cabins without extra space expansion. Integrated design with switchgear and monitoring equipment realizes one stop power transformation solution. The compact structural feature cuts civil engineering construction cost of new energy power stations and speeds up overall project delivery progress.
