Advanced application of multi-circuit measuring meter and wireless data transmission in solar photovoltaic power generation

Africa is a place with abundant resources and a large number of young population, but the development of manufacturing industry in Africa is not as prosperous as that of other emerging market economies in the world. The reason is that the development of manufacturing industry is largely limited by the lack of energy and sufficient power supply, but Africa deserves a better economy development. The lack of electricity has caused economic losses in Africa, accounting for 4% of its GDP, and greatly restricted Africa's economic development for a long time. While the power systems of African countries need to be developed, their solar and wind energy resources are quite abundant. For African countries, the development of new energy industry is feasible and necessary. Africa has a huge electricity supply shortage and has an immeasurable prospect of the solar power market. The potential installation capacity of its PV solar power plant projects is estimated to exceed 11GW. The installed capacity of its existing PV solar power plant projects is only in a few countries such as South Africa, Kenya and Morocco, mainly from large ground power stations, and the average scale is larger than that in mature markets such as Europe and the United States. During the period from 2022 to 2040, the new installed capacity of PV solar power generation is expected to reach 51GW. From the perspective of resources, that is, the direct solar irradiance, the development potential of the solar energy industry in Africa is undoubtedly the best in the world. According to the characteristics of solar photovoltaic power generation, the load is supplied by photovoltaic power generation during the day and the load is supplied by storage battery at night. In order to better demonstrate the energy distribution, optimize the overall efficiency and system reliability, the customer installed PD195-E33 series multi-circuit DC energy meters on the PV solar power generation

Application of Low Voltage Intelligent Capacitor in JP Compensation Cabinet of Shandong Province

1. Background introduction In recent years, with the deepening of urban and rural distribution network transformation, the demand for power consumption is increasing. The normal operation of various power equipment requires the power supply system to have good stability and efficient power supply capacity. However, in the process of power supply in the power system, since most of the electrical equipment are inductive load equipment, it reduces the power of the grid operation, increases the current reactive power, and causes a lot of power loss. At the same time, it also affects the normal operation of the equipment and accelerates the loss of the equipment. In order to reduce the negative impact of reactive power, using JP compensation cabinet for power compensation is an effective solution. JP compensation cabinet is a kind of common equipment to compensate power, and its core device is low-voltage capacitor. The application of JP compensation cabinet improves the overall operation efficiency of power grid.
