the reason why tbea sunoais established a team to specialize in developing svg products in 2013 is that it saw the inevitable trend of the world’s energy transformation. the volatility and discontinuity of new energy require advanced solutions to escort. choosing to develop svg products is based on new energy and provides reliable power equipment for new energy grid connection. now it seems that tbea sunoais has achieved landmark progresses in svg field. it is hard to imagine that they have achieved such a great transformation just in 7 years.
svg is a kind of typical power electronic equipment with the advantages of good dynamic reactive power compensation performance and supporting the compensation of unbalanced load and harmonic control, which will facilitate the friendly access of new energy. countries with multi-mainstream new energy development in the world require that new energy power stations and various impact load occasions must be equipped with a device similar to svg that can realize dynamic reactive power compensation.
once upon a time, the dynamic reactive power compensation equipment used in domestic new energy stations was almost monopolized by foreign power companies. however, within just 7 years, tbea sunoais has achieved a breakthrough from scratch and from weakness to strength in this field. by the end of 2020, the company’s svg products have been developed to the sixth generation with its stability, response speed and one-off operation rate in the leading place, becoming well-known quality products in the industry.
reviewing the past and striding forward
the reason why tbea sunoais established a team to specialize in developing svg products in 2013 is that it saw the inevitable trend of the world’s energy transformation. the volatility and discontinuity of new energy require advanced solutions to escort. choosing to develop svg products is based on new energy and provides reliable power equipment for new energy grid connection. now it seems that tbea sunoais has achieved landmark progresses in svg field. it is hard to imagine that they have achieved such a great transformation just in 7 years.
with the continuous mining of application problems and the technical breakthrough of difficult and painful points, the new products developed by lv lin’s team have made significant progress in the following years. he told the reporter, “first, the size of products of the second generation has been reduced by 30% and the cost has also been reduced accordingly. second, the degree of standardization of products has increased considerably. if the products of the first generation were customized tests, then the products of the second generation were engineered standards. third, the reliability of the products has been increased considerably. the subsequent products have continuously been upgraded and optimized, so as to be solid and delicate.”
high-quality products need to be recognized by customers. svg products of tbea sunoais are provided with reliable quality, fast response speed and 100% one-off operation rate. lv lin, general manager of the product line, told the reporter that the current online operation rate of equipment is more than 99.6%, far higher than the “double rules” assessment requirement of the power grid company to the power stations: the svg online operation rate is required to be greater than 95%. hence, the problem of customers being fined due to grid assessment was avoided.
there was a case in shandong province in the early years- the selected svg products were scheduled because of the “double rules” assessment, and the penalty was nearly hundreds of thousands per month. knowing the actual situation of the customers, tbea new energy has implemented the upgrading and transformation of the svg in the power station: the silica gel sealing encapsulation technology was used to improve the protection performance of the product, so as to improve its protective ability to cope with severe weather such as rain, snow, etc. from the product structure.
after this transformation, the rate of return of the power station has been greatly improved. not only were the monthly fines imposed by the power grid eliminated, but also the customer could get the reward of stable power supply. this action can save customers millions a year.
similar examples are too numerous to mention. it is the high recognition of the customers that keeps svg’s performance going forward. in only one month of december 2020, 156 sets of equipment were successfully put into operation and more than 100 new energy power stations were “installed” to ensure the power price reliably, reaching an all-time high. at present, tbea sunoais has successfully entered the first echelon of the domestic svg market.
it is like a shining “chinese business card” in both domestic market and overseas market, becoming the guarantee of quality and benefit. after several years of development, svg products of tbea sunoais from the middle east, australia, and turkey to pakistan are also recognized by international customers.
lv lin told the reporter that in 2019, in the middle east market, they cooperated with international general contractors. through field investigation and factory review, the general contractors made a comprehensive comparison in performance, reliability, response speed, price, quality and other aspects, and finally decided to use the svg products of tbea sunoais in saudi arabia’s largest ground photovoltaic power station project. the door to the middle east market was hence opened. after two years of efforts, by the end of 2020,tbea sunoais has provided svg products and services to power stations with more than 1.7gw pv in the middle east, becoming the only chinese svg manufacturer in the middle east and providing stable power quality guarantee for local photovoltaic power stations.
looking back on its development course, lv lin said, “we are a latecomer in the r&d of svg products. thanks to tbea sunoais and the company’s continuous investment of nearly ten million in the r&d of the field of svg products and power quality management, as well as the company’s attention to and training of talents, we could rush from this ‘red sea market’ all the way and surpass the formers.”
unified target infinite future
at present, svg products of tbea sunoais have been in the fifth and sixth generation, evolving from the original air-cooled models to the current liquid-cooled models. from the perspective of capacity, the new stand-alone machine has developed from the original 40mvar to the present 120mvar. the volume of the products has been reduced by about 50%. its application scope has been expanded from the new energy field to the subway, urban substation, ferrous metallurgy and other fields.
while talking about future development, lv lin said with certainty, “svg enjoys endless possibility in the future, which we are always exploring. svg is like a platform, with which we can drive our power equipment to continue to develop and make progress. we will be an integrated service provider rather than an equipment provider.”
in the future, new energy will be the main force of the power market, and svg will be the core guarantee of new energy connection and power transmission. in the transmission process, if the direct current transmission is used, svg must also be used in the converter station. in the power utilization end, with the large use of new energy vehicles, all the loads need to be electrified, and svg is also needed. hence, the application range of svg products will be increasingly wider, and svg products will become a late up-rising star in power equipment, providing equipment support for the development of new energy and power grid. because of continuous investment and active r&d of such enterprises as tbea sunoais etc., svg products in china can make progress. it is believed that tbea sunoais can still continue to maintain the development speed and technical advantages in the future, and write a new legend!
