Based on the above terminal hardware structure, various embodiments of the present application are provided.
The application provides a fan uninterrupted power supply system.
Referring to fig. 2, in a first embodiment of a fan uninterruptible power supply system, the system includes:
and the fan ring network switch is used for ensuring the stability of data transmission of the remote equipment maintenance system.
Wind power plant fans generally work in a severe environment, so that the working environment has the characteristics of humidity, acid and alkali corrosion, high dust and high electromagnetic interference, extreme cold and extreme heat and the like, and the wind power plant fans operate for years under the unattended condition, so that the wind power plant fans are guaranteed to be controlled reliably in real time. In a large wind power plant, dozens or hundreds of wind power generators are generally required to be monitored in a cluster manner, and a stable, reliable, rapid and real-time network system is required to be constructed. Therefore, in the project of the wind power plant, remote monitoring and information management of the wind turbine are important systems. In open field, optical fiber ring network equipment is required to be installed on each fan, so that data acquisition and uploading of the fans are realized, and centralized management and monitoring are facilitated. For a fan ring network switch, point-to-point connection and point-to-multipoint connection need to be supported, any two nodes in the ring network can communicate with each other, and point-to-multipoint broadcast communication can be realized, so that the stability of the whole ring network communication system is ensured. Because each fan looped network switch is important to the fan looped network communication system, each fan looped network switch needs to be ensured to be capable of carrying out normal communication at any time. Under the present general condition, all supply power to fan looped netowrk switch through fan looped netowrk direct current supply system, but as wind turbine generator system because of the reason such as case becomes trouble, fan loses the electricity, fan trouble, fan maintenance have a power failure, fan direct current supply system will fail to provide electric power for fan looped netowrk switch, will lead to fan looped netowrk communication to interrupt. When the ring network communication of the fan is interrupted, the operation condition of the fan cannot be monitored in time, and when the fan breaks down, the corresponding fault cannot be immediately processed, so that certain economic loss is caused.
The fan direct-current power supply system is electrically connected with the fan ring network switch and is used as a first power supply of the fan ring network switch;
the fan direct current power supply system can provide electric energy for the fan ring network switch. The direct current power supply system is reliable, can reduce the cost of being incorporated into the power networks and reduce the loss, consequently extensively regard as the power of fan looped netowrk switch, and direct current power supply system is relevant with the fan at that time, when the fan appearance case becomes the trouble, loses the power scheduling problem, will lead to direct current power supply system can't provide the electric quantity for fan looped netowrk switch to lead to fan switch outage and be the looped netowrk communication interrupt.

A conventional UPS (Uninterruptible Power System) can only supply Power for 1-24 hours (determined by the load and the capacity of the battery) when an external Power supply is interrupted, and cannot supply Power continuously when the fan is interrupted for a long time. The solar uninterruptible power supply system can generate electric energy by using solar energy, the solar energy is relatively easy to obtain, uninterrupted electric energy supply can be guaranteed when conditions allow, and uninterrupted power supply can be guaranteed for a longer time.
The solar uninterruptible power supply system comprises a solar panel, a power supply controller and a storage battery pack.
Under the condition of fan power loss and in the daytime that the solar energy is sufficient, solar cell panel can absorb solar energy and convert the electric energy into and export for fan looped netowrk switch, with unnecessary electric energy storage in storage battery simultaneously, in the environment that is in solar energy insufficient, when the electric energy that produces through solar cell panel can't satisfy the electric power demand to fan looped netowrk switch promptly, then charge for the looped netowrk switch through the electric energy in the storage battery. Meanwhile, a power controller in the solar uninterruptible power supply system can acquire the states of the solar cell panel and the storage battery pack, so that corresponding charging and discharging control is performed.
In this embodiment, for fan looped netowrk switch provides fan direct current power supply system and solar energy uninterrupted power supply system as power supply, different power supply can be simultaneously for the fan switch power supply, after one of them power supply (generally fan direct current power supply system) interrupt, another power still can normally work, solar energy uninterrupted power supply system passes through solar energy storage electric energy daytime, under emergency, can utilize the electric energy of storage to last the power supply for the looped netowrk switch, and reuse solar energy storage electric energy daytime again, thereby ensure the communication function normal use of fan looped netowrk switch.

When the plurality of power inputs have corresponding fan direct-current power supply systems as power inputs, namely no idle power input interface exists, the newly added solar uninterruptible power supply system is connected in parallel with one of the fan direct-current power supply systems and then connected to the power interface. The solar uninterruptible power supply system is used as a power supply system capable of continuously providing electric energy for a long time, and when other fan direct-current power supply systems lose power, the solar uninterruptible power supply system can provide electric energy for the ring network switch to ensure that the ring network communication of the fans is uninterrupted.

When the ring network switch is used for multi-power input, when not all power input interfaces have corresponding fan direct current power supply systems as power input and at least one idle power input interface, the solar uninterruptible power supply system is connected into the ring network switch through the optional idle input interface, and then when other fan direct current power supply systems lose power, the communication of the ring network switch can be ensured to be uninterrupted through the electric energy of the solar uninterruptible power supply system. Referring to fig. 5, the ring network switch is a dual power input, one of the power inputs is a fan dc power supply system, and the other power input is a solar uninterruptible power supply system, under normal conditions, the two power inputs can simultaneously provide electric energy for the ring network switch, and when the fan dc power supply system loses power, the solar uninterruptible power supply system can still normally provide electric energy for the ring network switch, thereby ensuring that the ring network communication is not interrupted.
