Description

technical field [0001] The invention belongs to the field of photovoltaic power plants, and in particular relates to a reactive power compensation device for photovoltaic power plants. Background technique [0002] With the development and progress of science and technology, people's requirements for things have changed from the old thinking that can be used to become quite delicate and demanding. Only the idea of ​​continuous improvement or innovation will produce new forms to increase the added value of products. , in order to survive under the test of fierce market competition. [0003] The loads of photovoltaic power station projects are mostly inductive loads. A large number of inductive loads not only cause the system power factor to be too low, reduce production efficiency, and increase the power expenditure of the enterprise, but also cause voltage fluctuations in the grid, which will affect the safe operation of the load equipment and bring unnecessary economic los...

Problems solved by technology

Therefore, the reactive power compensation device is in an indispensable and very important position in the power supply system. Reasonable selection of the compensation device can minimize the loss of the network and improve the quality of the power grid. On the contrary, if you choose or use Improper power supply system, voltage fluctuation, harmonic increase and many other factors may be caused. The traditional reactive power compensator has a single structure, poor heat dissipation, weak earthquake resistance, and poor dustproof ability. Directly lead to damage to the internal components of the compensator, resulting in economic losses
