To start the domestic PV market, the Ministry of Finance, the Ministry of Industry and Information Technology, Ministry of Commerce, the National Energy Board issued a series of multi-sectoral favorable policies to support industrial development. But in the grid links and technical aspects of the standard size of the domestic photovoltaic applications, there are many difficulties.
In order to make the plant run more smoothly and efficiently, more standardized industry standards, the State Grid Corporation released a new national standard GB/T19964-2012 "photovoltaic power stations connected power system technical requirements", the standard released to protect the large-scale photovoltaic power system after network stable and reliable power supply security, and promote the healthy and orderly domestic photovoltaic power generation rapid development, but at the same time the various components of the PV power plant suppliers put forward higher requirements. Especially in the pure sine wave inverter the new standard for access at a higher level of active power inverter, power prediction, low voltage ride, run adaptability, simulation models and parameters provided for.
As an industry leader in sun power inverter brand in 2013SNEC show released four new products. One of the most representative to lead the industry wind SG500MX inverters are the only new national standard GB/T19964-2012 "photovoltaic power stations connected power system technical requirements" Test of photovoltaic inverters. This section first inverter high voltage ride through a national network of detection, to achieve high voltage withstand the highest standards, through low-voltage, zero voltage across the test, calmly deal with various complex network environments.
SVG features along with the night, all-weather response dispatching instruction; adjustable reactive power, power factor range ahead of the 0.9 to 0.9 lagging. SG500MX Another advantage is that the inverter AC and DC wiring space can be larger, more user-friendly operation, the integrated DC distribution function, saving the user equipment and operation and maintenance costs, while optimizing the dynamic MPPT control strategy, higher power output. As the only one with new standards, new national standard PV inverter has a strong market appeal, sun power inverter believe this model will be further recognized by many customers.
The release of the megawatt-class container pressure system integration solutions SG1000TS-MV is a turnkey solution, high integration. The product integrates photovoltaic photovoltaic inverter AC and DC power distribution, medium voltage transformers, RMU, system monitoring, fire alarm, environmental monitoring and other functional modules, but also saves a lot of communication cable, reducing the loss of customers to create higher economic benefits. Product is equipped with SCADA monitoring system, to achieve convergence, power distribution, inverters and other aspects of real-time data collection and monitoring, data analysis more comprehensive and more timely response to save power station operating personnel costs, more efficient power plant operators to maintain the best condition.
