Solar Energy And Its Energy Saving Effect Of Variable Frequency Pump System

In order to solve the current problems of energy shortage and environmental pollution, it is necessary to develop and make use of solar energy, solar energy is inexhaustible in supply and always available for use, it is also an clean renewable energy. The use of solar energy will be regarded as the main content of the sustainable development in the future. Solar water pump system is a typical means of efficient use of solar energy, it convert solar energy into electricity to drive the pump running. The 12thFive Year Plan has made it quite clear that the pump motor speed regulation technology is an important means of energy saving. The advantages of high accuracy.high efficiency and high performance make it become the preferred device design. This design through a comprehensive study of solar water pump system and frequency conversion speed regulation system of constant pressure, combining the two systems used in the actual water supply project, it will have a very large economic benefits and application prospects.This design mainly based on the test pump of WQ3-20-0.75, through the analysis of the performance parameters of the solar system and reasonable configuration, such as the selection of solar panels, battery inverter frequency converter design, etc, make it has a stable power supply during the operation process. Analyze the performance parameters and size, comparison several water supply scheme, it is concluded that variable frequency constant pressure water supply is the most suitable operation conditions and energy saving, Make analysis and calculation of the configuration of constant pressure equipment. According to the reasonable and effective collocation of two systems makes it a an complete solar variable frequency pump system, and it carries on the cost comparison and the energy conservation effect analysis.Through the experimental study on the design of the whole system and energy saving effect analysis of the processing of the test data validation, it found that solar power variable frequency pump system energy saving effect is remarkable. It is practical in economic application, and will have broad prospect of application and social and economic benefits.
