Abstract: A compact rotary algae biofilm reactor includes an algae biofilm module and a light guide module. The algae biofilm module includes a plurality of rotary members and a reaction tank. In the rotary member, an algae biofilm growth carrier and a power transmission belt are wound on a driving shaft and a driven shaft. A top end of the rotary member is fixed on a fixing frame while a bottom end thereof is submerged in the reaction tank. The light guide module includes a rotatable lens holder. The rotatable lens holder is fixedly provided with a linear Fresnel lens on an upper end thereof and is provided with a light guide plate on a lower end thereof. One side of the linear Fresnel lens is provided with a step motor configured to control the linear Fresnel lens to rotate with an angle of sunlight.

Abstract: The present invention relates to a monitoring and controlling system and method for megawatt level battery energy storage power plant, which includes: a central monitoring and controlling module is used to determine the power command value of each energy storage substation of the battery energy storage power plant, and send it to all the local monitoring and controlling modules; the local monitoring and controlling modules is used to calculate the power command value of each energy storage unit of the energy storage substations controlled by it, and sending it to each energy storage unit, and upload to the central monitoring and controlling module to store. Between the central monitoring and controlling module and the local monitoring and controlling modules, the data transmission and communication are carried out through communication networks; the communication networks adopt real time and non real time communication parallel network structure.
