Kehua Hengsheng Hengsheng PV Technology has been recognized: - 500KW grid-connected photovoltaic inverter successfully completed the LVRT test and zero voltage ride-through test.
Recently, Kehuan Hengsheng Hengsheng issued new news. SPI series 500K-B model 500KW photovoltaic grid-connected inverters have been in the National Energy Solar Power Research (Experiment) Center of China Electric Power Research Institute on August 24, 2012. In accordance with the State Grid Corporation of China Q/GDW 617-2011 “Technical Regulations for the Intervention of Power Grids for Photovoltaic Power Plantsâ€, the Low-Voltage Ride-Through (LVRT) test and zero voltage ride-through test were successfully completed. The passing of this test indicates that Kehuan Hengsheng Goldman not only became the first domestic company to pass the zero-voltage ride-through test, but also became one of the few companies at home and abroad that can simultaneously pass the two tests. The high-power photovoltaic grid-connected inverters of Kehuan Hengsheng Hengsheng have reached the leading level of similar products in the industry.
The so-called "low-voltage ride-through test (LVRT) test", commonly known as "low-voltage ride-through test" in Chinese, is a kind of technology that can ensure that the grid-connected inverter can remain off-grid and even to the grid when a short-circuit or voltage drop occurs in the power grid due to a fault. Inject a certain amount of reactive power to help the grid recover, stop the supply of dynamic voltage, cross the obstacles in the short circuit, and ensure the stable and normal operation of the power grid. The zero voltage ride through test means that when the PV voltage of the photovoltaic power station drops to 0, the photovoltaic power station should not be off the grid and run continuously for 0.15 s. Compared to the low voltage ride through (LVRT) low voltage ride through, zero voltage ride through to the grid The performance and technical requirements of the inverter are higher, and the photovoltaic power station can ensure more stable operation. According to the latest National Energy Bureau and State Grid Corporation's requirements for grid-connected generation of photovoltaic power plants, in order to prevent photovoltaic power plants from collapsing in the entire power grid caused by a voltage drop caused by a power grid failure, resulting in a large-scale power outage, photovoltaic inverters that are required to be connected to the grid for power generation Both must have low voltage ride through capabilities. Because the zero-voltage ride through test is more demanding and more demanding for photovoltaic grid-connected inverters, only a few companies in China can successfully complete zero-voltage detection, but as national grid-connected systems improve the safety of photovoltaic grid-connected networks, The detection of these two double items will be the only choice for future photovoltaic companies.
It is reported that, shortly before, Kehua Hengsheng's "High-power solar photovoltaic grid-connected inverter SPI100K, SPI250, SPI500K" project has been successfully selected in the 2012 national key new product plan. Through policy guidance and support, the plan has accelerated the construction of China's scientific and technological industrialization environment and greatly enhanced the international competitiveness of China's products. As a leader in smart energy, Kehua Hengsheng has always been adhering to the development concept of "independent innovation, own brand" and is committed to building a core competitiveness with high-tech electric energy technology. Therefore, for this LVRT test, project team members will exert their efforts Go with the cooperation.
At present, the Low Voltage Ride Through (LVRT) "LVRT Test" and zero voltage ride through test have become important technical requirements for the global solar photovoltaic power generation and wind power industry. Many foreign countries have listed it as a mandatory requirement, August 2011. In order to stabilize the safety of photovoltaic grid-connected inverters, China also imposes mandatory requirements on this function, and domestic and international photovoltaic inverter project bidding has already adopted low voltage ride through capability as a threshold for entering the photovoltaic field. And zero voltage detection can also provide excellent support for the product's performance. Therefore, the Kehuan Hengsheng SPI Series 500K-B 500KW high-power photovoltaic grid-connected inverter successfully passed the dual-entry inspection and will be a great test for the overall operating capability of the comprehensive strength of Kehua Hengsheng Hengsheng new energy products. And fully affirmed.
In addition, Corvus Hengsheng's "High-Power Solar Photovoltaic Grid-connected Inverters SPI100K, SPI250, SPI500K" project was also successfully selected for the 2012 national key new product plan. The purpose of the plan is to speed up the construction of China's scientific and technological industrialization environment through policy guidance and support, and greatly enhance the international competitiveness of China's products.
It is believed that this Kehuan Hengsheng test will demonstrate that the SPI 500K-B 500KW high-power photovoltaic grid-connected inverter fully meets the stringent requirements of the State Grid “Technical Regulations for PV Power Plants Involving Power Grids,†which signifies Kehuaheng. Sheng's PV market is more competitive and its product grade and technical level have reached a new level. It fully meets the conditions for undertaking large-scale PV power plant projects and will provide strong technical support for China's vigorous development of solar power grid-connected technology applications. At the same time, it also fully embodies the strong technical strength of Kehuan Hengsheng as a high-quality, professional photovoltaic inverter company, and provides a strong guarantee for the national key new product plan.
