STD TRANSFORMERS FOR SOLAR POWER PLANTS

STD Transformer give privilege to not consuming world resources while generating energy resources…

PRODUCTION PROCESS

STD Transformers are manufactured to provide a high quality and reliable transformer to the end user. Utilising Quality-Oriented Manufacturing (QMS) platform, which defines design standards, equipment and processes used in its facilities. Use of this Common Technology enables STD to guarantee customers a high quality and consistent product. The transformer is a static inductive device that can step the voltage up and down to transfer electrical power efficiently. Winding types and methods that offer the least loss were selected using magnetic field analysis and used in the STD Transformers to ensure high levels of efficiency.

Moreover, by selecting the optimal insulating structure through the electric field analysis of insulation between turns, sections, windings and phases, the Transformer’s electrical stability is achieved. STD fluent analysis technology has enabled the realization of an optimal cooling system, and 3 structure strength analysis has enabled a structural design that can withstand internal mechanical power short-circuits caused by system faults, seismic conditions according to external impacts, and the impact of transportation.”

STD’s factory is equipped with the latest core processor machines, the latest technology winding formation machines, high-capacity vacuum heat drying equipment, state-of-the-art cleaning facilities including State of the Art and Challenges for Occupational Health and Safety Performance.

CLEAN ENERGY SOURCE

Solar energy is a renewable clean energy source the, safest, and most reliable energy source of the future. Photovoltaic power generation is an efficient use of solar energy., the different types of solar transformer are: Step-up transformers, step-down transformers, distribution transformers, substations, pad mounted and grounding, dry-type transformers, etc., STD produces various types of transformers of different power and voltage complying with international standards such as IEC 60076 and ANSI, BSI, IEEE, NEMA, TS EN 60076, IS:2026 with its registered ‘STD’ brand within the scope of ISO 9001, ISO 14001, OHSAS 18001.

STD supplies transformer solutions to dozens of solar power plants. Based on international experience, STD has available transformers for photovoltaic power plants with large capacities, many low-voltage branches, high temperature limits, compactness, high secondary integration and ease of installation and use, which are used in a large number of applications in the photovoltaic power generation sector.

SOLAR ENERGY TRANSFORMER SOLUTION FROM STD TRANSFORMATOR FOR APPLICATION IN DISTRIBUTED PHOTOVOLTAIC (DPV)

Within DPV Power Generation Systems, electricity is produced through the conversion of solar radiation into direct current (DC) electricity with semiconductors that show the photovoltaic (PV) effect. Photovoltaic power generation is based on solar panels made up of an array of photovoltaic modules (cells) that contain the photovoltaic material. It is typically composed from silicon. The PV module is able to produce a voltage as high as 1100V (DC).The resulting DC voltage is transformed into three-phase AC voltage by using a three-phase inverter. The inverter then connects to an DPV the system’s inverter transformer to facilitate the distribution of the alternating current (AC) electricity. From rooftops for residential homes to industrial and commercial applications and utility-grade power plants STD’s suitable solar distribution transformers are specifically matched to various size solar inverters and their functions.

DRY-TYPE TRANSFORMERS FOR SOLAR POWER GENERATION

When the sun is strongest, it is the highest ambient temperature of the dry type of solar transformer, and the transformer output power is also in the maximum state, so the temperature of the transformer reaches the maximum, but at night, the transformer is basically in the no-load state and the ambient temperature is low.

Therefore, the temperature of the solar power transformer is lower at this time, which can compensate for its aging life. Therefore, when designing the temperature rise of the transformer, full consideration should be given to its load and ambient temperature fluctuation characteristics, and the maximum temperature on the solar power transformer should not exceed the magnetic density of the insulation material and insulation structure.

STD Cast Resin Transformers have at least one of the two windings embedded on an autoclave mould, at vacuum values close to zero with epoxy resin. The other winding can also be cast in H class. STD Cast Resin Transformers have reached a high degree of reliability thanks to the technological advances in recent years. STD production E2, C2, F1, but also E3 (IEC 60076-16) and C4 (GOST-R), can be used in the presence of a high humidity and pollution rate, low installation temperatures even down to -60°C, therefore eliminating the problems related to the risks of fire and emissions of toxic and harmful substances in case of fire.

These Transformers are entirely built with insulating, flame retardant and self-extinguishing materials, they are completely free from all restrictions that should normally be applied to flammable equipment with a danger of spreading fire. Power Rating : from 50kVA up to 2500kVA.Voltage Level : from 1,1kV up to 36kV. Frequency: 50 or 60Hz Vector Group: single phase or three phase transformers with possibility of star or delta connections in any of its windings. Number Of Windings: possibility to manufacture transformers with primary + secondary, double secondary and any other type according to requirements of customer. Cooling: according to EN/IEC 60076, AN, AF.
