5 results about "Standby generator" patented technology

This invention relates to the field of solar power generation technology, specifically to a generator set for a solar energy device. The generator set includes a pile foundation, with a pipe rotatably connected to the outer side of the top of the pile foundation. A floating part is fixedly connected to the outer side of a transmission ring. The floating part includes two mutually fixed float plates, a first float plate and a second float plate. Multiple drive components are fixed at equal angles on the bottom surface of the second float plate, each drive component including a housing with blades rotatably connected to it. A photovoltaic module is mounted on the top of the second float plate, comprising multiple photovoltaic panels and an adjustment frame. In this invention, by having multiple photovoltaic panels supported on the second float plate at a large tilt angle to receive sunlight, and by having multiple blades at the bottom of the second float plate rotate to drive the float plate carrying the multiple photovoltaic panels around the pile foundation, the photovoltaic panels can automatically adjust their direction of sunlight reception according to changes in the direction of sunlight, thus improving the efficiency of photovoltaic power generation.

A procedure for operating an electrical energy system in a building includes a step for collecting a variety of consumption data on the electrical active energy drawn. This active energy is drawn from the public electricity grid and / or from existing energy generators within the building's energy system via a grid connection point. A load profile is determined based on the consumption data. This load profile describes the expected or historical trend of the active energy drawn over a given period. A backup generator for generating and / or supplying electrical energy is then selected based on the load profile. The backup generator is intended to operate instead of, or in addition to, existing energy generators within the building's energy system and / or to reduce the amount of active energy drawn from the public grid.

This invention relates to the field of automatic management technology for ship power plants, specifically to an automatic management system and method for ship power plants based on load prediction. The system includes a load prediction module that receives multi-source data acquired by a data acquisition and fusion module and outputs a predicted load curve for the ship using a pre-trained load prediction model. An optimization decision module dynamically calculates the ship's safety margin based on the predicted load curve obtained by the load prediction module and dynamically generates start-up, shutdown, paralleling, and disconnection control commands for the ship's generator sets. By predicting the future load curve of the ship, this invention can start standby generator sets in advance before the predicted overload risk point, ensuring that paralleling and load transfer are completed before the peak load arrives. This effectively avoids the risk of overload tripping due to generator start-up delays and greatly enhances the robustness of the ship power plant.

This invention provides a method for calculating the optimal generator configuration scheme based on ship electrical load. The specific steps include: determining the power requirements of each functional module under different operating conditions, and determining the total power required for each operating condition. Functional modules include: electric propulsion equipment, dual-fuel supply system, engine room auxiliary machinery, air conditioning, refrigeration and mechanical ventilation, deck machinery, maintenance equipment, galley and laundry equipment, electrical equipment, and mechanical ventilation when refrigerated containers are installed in the cargo hold. Operating conditions include: navigation, departure without side propulsion, departure with side propulsion, loading and unloading, and berthing. Generator configuration schemes are generated based on at least the total power and configuration information for all ship operating conditions. Configuration information includes: the total number of generators and the load rate requirements and / or the number of standby generators for the corresponding operating conditions. All generator configuration schemes are pre-screened for maximum load conditions and load rate limits. Cost screening is performed on the screened schemes to output the target generator configuration scheme.
