Embodiment 1
[0050] Such as figure 1 As shown, an intelligent operation and maintenance method for photovoltaic power plants based on building information model: use the three-dimensional model to accurately locate the equipment, and realize it by automatically calculating the position of each minimum equipment unit in the model. According to the GPS location information of two fixed buildings in the power station, the position of each minimum equipment unit in the model is automatically calculated, and the equipment is accurately positioned as a carrier model for the operation and maintenance management of the power station. The process of automatically calculating the position of each minimum equipment unit in the model includes:
[0051] Calculate the distance between two GPS [A (LonA,LatA), B(LonB,LatB)] by using the spherical radius R of the earth and the latitude and longitude, Dab=R*arccos [sin(LatA)sin(LatB)+cos(LatA)cos (LatB)*cos(LonA-LonB)];
[0052] According to the distance ...

The invention relates to an intelligent operation and maintenance method and system for a photovoltaic power station based on a building information model, and the method comprises the steps: collecting the operation and maintenance data of the photovoltaic power station; judging abnormal equipment; locating an abnormality precisely, calculating the position of the smallest equipment unit in a model according to the GPS position information of two fixed buildings of the power station through employing a power station building information model, and precisely locating the equipment. carrying out the routing inspection of the abnormal equipment; and maintaining the abnormal equipment. The system comprises the functions of a system background and services, the function of a three-dimensional model, the function of a computer end application platform, and the function of a mobile end application platform. The beneficial effects of the invention are that the method solves the actual operation and maintenance problems that the equipment abnormality cannot be found timely in an operation process of the photovoltaic power station, the decrease of the operation efficiency of equipment cannot be found timely, the operation and maintenance team has a large workload in routing inspection and the locating of equipment is difficult; meanwhile, the method helps the photovoltaic power station improve the productivity and benefits, reduces the operation and maintenance cost, and improves the rate of return on investment.
Description
technical field [0001] The invention relates to the technical field of photovoltaic power generation, in particular to a method and system for intelligent operation and maintenance of photovoltaic power plants based on building information models. Background technique [0002] Photovoltaic power station operation and maintenance is a comprehensive business behavior that integrates equipment monitoring, inspection, inspection and maintenance, analysis and decision-making, and related affairs management. In the past, the operation and maintenance of photovoltaic power plants were mostly professional monitoring and manual inspection, and the inspection and maintenance information was recorded in a relatively independent inspection and maintenance management or equipment management system, and then multi-systems used artificially synthesized reports as post-event analysis to provide reference for decision-making. [0003] In the actual business development, the overlapping delay...
