The TC-3060 generator reverse power protection device is suitable for small power supply systems such as small generators or distributed power supplies. The photovoltaic power station is used as an example。When the photovoltaic power station is designed without reversible grid-connection, reverse power protection equipment should be configured。The device is mainly suitable for 380V voltage level inverse power monitoring device, while the distributed inverter control, so as to achieve the rated output of the photovoltaic power station level regulation。Finally achieve the following two aspects of the requirements, on the one hand, the power supply department needs to ensure the quality and reliability of the power supply of users, while making the clean power supply can work normally, and give full play to the economic benefits and demonstration role of clean energy。On the other hand, the operation of the clean power supply should not affect the safety of the power system, do not allow the clean power supply through the power transformer or low-voltage inlet line to the public grid, while the most scientific and reasonable use of clean power supply to reduce the cost of electricity for users。Therefore, it is necessary to carry out safety control on clean power supply。
When the device is used in the low-voltage generator loop, the device monitors the generator side loop in real time, and determines whether there is reverse power in the loop by monitoring the three-phase voltage (380V) and the three-phase current。If power is reversed to the generator side, the device quickly cuts the circuit breaker to protect the generator and the circuit。
When the device is used in photovoltaic power station, the task is to monitor the low-voltage side of the distribution transformer in real time.Necessary control of clean power supply。The microcomputer device and control circuit specially designed for it can ensure the rapidity of the protection action and the accuracy of the control。
