The Railway station house has high requirements for the application of the lighting system, the intelligent control technology applied to the Railway station house lighting design, contribute to better energy saving and environmental protection from the perspective of improving the management level of the Railway station house lighting, for the development of green construction of the Railway station house lighting system and the application of intelligent technology is of practical help.

Photovoltaic power generation, as a new and pollution-free power generation method, has greatly alleviated the demand for traditional electric energy. However, for the grid-connected photovoltaic power generation system, due to its inherent randomness, volatility, and intermittent characteristics, and the grid-connected photovoltaic power generation system contains a large number of nonlinear power electronic components, compared with traditional power generation methods, photovoltaic power generation has The power quality of the grid has a great impact. This article analyzes the harmonics, voltage fluctuations and flickers, DC injection, islanding effect and other problems caused by grid-connected photovoltaic power generation on the power grid, and studies and discusses feasible measures to improve power quality.

With the widespread use of electronic devices, non-linear loads are increasing, which results in that the harmonic pollution in enterprise power grids is becoming more and more serious. Due to the adverse effects of harmonics, the quality of electricity is deteriorating, the additional losses increasing, the reliability of the power grid reducing, so that the normal operation of enterprise power supply and consumption equipment is affected, and even equipment is damaged to cause electrical faults. Based on the requirements and current situations of electricity safety, this paper analyzes the functions and effects of active filter devices in biopharmaceutical safety power supply systems.
