The invention relates to a novel electric power system power supply capability evaluation and prediction technology, in particular to an improved wind and light field station level power supply capability evaluation and medium and short term prediction method and device. A novel comprehensive evaluation index system for the power supply capability of the power generation side of the power system is constructed from two dimensions of output reliability of renewable energy sources and adjustable capability of an energy storage system; in the aspect of power supply capability prediction, an empirical mode decomposition-kernel principal component analysis-long short-term memory neural network prediction algorithm EMD-KPCA-LSTM improved by a sliding window method is provided. The method can effectively overcome the limitation of a new energy station power supply capability evaluation method based on a traditional output concept, can more comprehensively reflect the actual power supply capability of the power generation side of a novel power system, can better process nonlinear and non-stationary data, captures the long and short term dependency relationship in time series data, and improves the power supply capability of the new energy station. The method has certain advantages in new energy power supply capability prediction.

This invention provides a hybrid energy system based on tower solar power generation and proton exchange membrane fuel cell combined power generation, along with waste heat multi-effect distillation for saline-alkali water desalination, belonging to the field of hybrid power generation technology. The system includes: a tower solar power generation module, a proton exchange membrane fuel cell module, a power management module, and a waste heat-utilizing saline-alkali water desalination module. This invention combines tower solar power generation and proton exchange membrane fuel cell for power generation, efficiently recovering low-grade heat from the proton exchange membrane fuel cell power generation process for saline-alkali water preheating and efficiently recovering high-temperature steam heat generated during the tower solar power generation process for saline-alkali water desalination. This promotes the upgrading of solar power plants in areas with abundant solar resources but predominantly saline-alkali groundwater, as well as on outlying islands, and also meets the local freshwater supply needs for production and daily life, avoiding resource waste while further improving power generation efficiency, making it more energy-efficient and environmentally friendly.

In a typical on-site solar table assembly process, multiple solar modules are securely aligned and attached to a shaft or torque tube to form a row of solar panels. An installer uses a fastener to attach a mounting bracket to a panel frame securely. A typical installation is implemented manually by an installer. To implement automatic fastener installation, fasteners must be loaded into an automatic installation tool in the correct orientation. Embodiments of automatic wedge alignment are disclosed to improve solar table assembly efficiency. Fasteners are aligned longitudinally and separated into forward-oriented and backward-oriented fasteners output from different pairs of output rails. Applying the described embodiments may improve solar table assembly efficiency so that the overall construction process for large solar plants may be completed more efficiently.

A cable management system is designed to support a cable in a solar plant. The cable management system includes a U-shaped bracket and at least one clip half. The U-shaped bracket has a base with two arms, each arm including a securing slot. The clip halves have a top portion, a bottom portion, a front portion, a rear portion, and a side portion from which the button pad extends. The clip half is mounted within the U-shaped bracket such that the button pad slides in the securing slot to position the clip half in the U-shaped bracket. The clip halves space and support a cable mounted in the U-shaped bracket.
