Photovoltaic energy has become the most potential and advantageous renewable energy source. Due to photovoltaic applications, photovoltaic power generation has gradually entered ordinary people's homes in forms of ground photovoltaic power stations and roof photovoltaic power stations. Therefore, it is necessary to understand photovoltaic power generation from various angles. 1. Why should we pay attention to the quality monitoring of distributed photovoltaic power generation system? Firstly, distributed photovoltaic power generation systems are mostly combined with buildings. If there is a problem in system quality, it may not only cause damage to the internal equipment of the power generation system, but also endanger the safety of the power distribution station and the surrounding personnel of the building. Secondly, distributed photovoltaic power generation systems are mostly for personal use. If there is a problem in system quality, it may cause damage to the electrical e

In laboratory monitoring projects, different laboratories have requirements for temperature and humidity, and most of the experiments are conducted in an environment of clear temperature and humidity. Laboratory environmental conditions directly affect the results of various experiments or tests. Accurate and reliable monitoring instruments are required to provide accurate environmental parameter data for each experiment. The key factor to be considered in temperature and humidity control under environmental conditions is to ensure that the environmental temperature and humidity of the experimental operation can meet the needs of each process of the experimental program. We mainly formulate the range of laboratory environment temperature and humidity control from the following aspects. First of all, identify the requirements for environmental temperature and humidity. We mainly identify needs of instrument, reagent and experimental procedures, and humanistic considerations for l

There are a large number of nonlinear, fluctuating and impulsive loads in the actual electric energy system, such as electric locomotives, semiconductor rectifiers, inverters, frequency converters, electrified railways, induction heating furnaces, electric arc furnaces, electric arc steelmaking furnaces, rolling mills, etc. These loads in industrial and domestic equipment cause waveform distortion (harmonic), three-phase imbalance, flicker, voltage fluctuation and asymmetry in the power grid, which seriously reduce the electric energy quality of the power grid. At the same time, the acceleration of wind farm construction in recent years also has some impact on electric energy quality. Precision electronic instruments controlled by computers and microprocessors are widely used in national economic enterprises, and are more and more sensitive to quality of electric energy supply. Therefore, higher requirements are put forward for electric energy quality, which makes problems of electric
