In recent years, the stability of Taiwan's electricity has become a major concern, and wind and solar power, which are green energies along with hydroelectricity, have once again become one of the main focuses of discussion. As Taiwan is one of the world's leading technology centers, the importance of ensuring energy security and stability is self-evident and means that the development of renewable energy has become a key issue in accelerating the energy transition. As a result, green and clean energy sources such as photovoltaic and wind power are attracting much attention, and their installed capacity continues to break new heights.
In wind power and photovoltaic fields, inverters are one of the very important key components. Inverter is a kind of equipment that can convert DC power (battery, storage battery) into AC power (generally 220V, 50Hz sine wave), also known as inverter power supply. Its output of AC power can be used in various types of equipment, to maximize the mobile power supply sites or powerless areas to meet the needs of users of AC power, is now widely used in office equipment, living appliances or the need to use batteries in the equipment.
In green power grid systems, in order to couple small hydroelectric plants/photovoltaic systems to the public grid, or to connect wind turbines in wind power plants to the public grid, the inverter must have a network and system protection (NA protection) device to continuously check the status of the grid and to decouple the system immediately in the event of a fault. This prevents unnecessary islanding, which can be dangerous for maintenance personnel. Due to different standards in different countries, inverter manufacturers often need to fulfill different standards in different countries in one device.
Honghong NA protection equipment has a flexible wide-area network that enables functional safety and silo detection, is freely programmable and can be freely configured directly in the field, and has been pre-installed with a large number of feature-country/region-specific parameter settings to meet the requirements of most countries/regions.
In addition, in order to avoid feeding excess energy into the power grid and to make effective use of the energy generated by the photovoltaic system, it is possible to connect the HK-G2IA15A monitoring relay after the inverter as a current measurement module. In the rooftop PV scenario shown below, the HK-G2IA15A is able to measure the amount of power generated and the output analogs are correlated with the control electronics of the heat pump, so that if the PV system generates excess energy, this energy is used to heat the hot water buffer tank, thus avoiding wasted energy.
In addition to the above solutions, Honghong has also introduced other solutions in the field of renewable energy, such as the HK-P-4.0 soft starter to help maximize solar energy harvesting from photovoltaic systems.The most important and fundamental task of a photovoltaic system is to capture as much solar energy as possible for energy production through solar modules. The most important and fundamental task of a photovoltaic system is to capture as much solar energy as possible for energy production through solar modules. This is why photovoltaic tracking systems are used, which can track the changing position of the sun during the day. The continuous, stepless movement of the panels is necessary to avoid damage and failure of the mechanical structure.
Combined with a radiation sensor, the HK-P-4.0 soft starter requires only two inputs and no contactors to reliably capture solar energy at any time. Acceleration time, torque and motor protection can be easily set using the rotary switch on the front of the device. The soft start and stop process protects the shaft and drive belt from mechanical overload. Due to the very low energy consumption, the HK-P-4.0 soft starter ensures maximum efficiency and a high return on investment.
The power industry is an important sub-sector for economic development, and green power is essential for building an environmentally friendly, pollution-free and healthy environment. Honghong offers domestic customers a wide range of cost-effective and high-quality products, including relay protection, grid and system protection solutions, as well as HSR/PRP solutions for building smart grids.
