BBU27-40E application field and working principle

BBU27-40E is a type of high-voltage direct-current (HVDC) converter, which is composed of two three-phase HVDC converters connected in series by an insulation transformer. It is widely applied in the fields of electric power transmission, renewable energy integration and so on.

The main function of the BBU27-40E is to control the power flow between two DC systems or a DC system and an AC system. It can realize the bidirectional power flow control, electric energy storage and power exchange between different systems, helping to solve the problems of frequency instability and disturb the power grid caused by large-scale energy transfer. This also facilitates the optimal allocation of electric energy resources and the development of renewable energy.

The working principle of the BBU27-40E basically involves the conversion of high-voltage direct current into the opposite side\'s alternating current by direct current voltage and then transmit the energy to the end user. It\'s a complex mechanism that requires precise control of speed, power and temperature to ensure its continuous reliable operations.

When operating, the valves of the BBU27-40E form a high-frequency current and a low-frequency current system, which change their direction of electric energy continuously and regularly according to the control of the microcomputer. The energy is converted between AC and DC, so that the BBU27-40E can realize the control of DC source to AC or DC, and can also realize the opposite controlling. Simultaneously, the energy can also be stored during DC charging or discharging process, which is beneficial for the utilization of power source energy.

In conclusion, BBU27-40E is a type of high-voltage direct-current converter that is widely used for energy storage, power transmission, and control of power flow in different systems. It has the advantages of high efficiency, accurate power control and a stable operation. Its working principle involves the conversion between AC and DC according to precise control of speed, power and temperature, and is beneficial for the optimal allocation of electronic energy resources and development of renewable energy.
