Independent photovoltaic power generation railway power supply control system and control method thereof

Abstract

The invention relates to an independent photovoltaic power generation railway power supply control system and a control method thereof and aims to solve the problems that equipment with special requirements such as large impact load and communication signal highly-stable load exists in railway electric equipment, solar photovoltaic power generation is largely influenced by environments, and low solar energy conversion efficiency and power insufficiency of a power supply system commonly exist in a photovoltaic power generation system. Solar radiation energy is collected and converted into direct-current electric energy, a storage battery pack is charged after conversion, the direct-current electric energy is converted into alternating-current electric energy for loads, load working voltage and current information monitored by a working state collector and environment information monitored by a environment illuminance collector and a environment temperature collector are transmitted to an energy accumulation system controller, and the information is logically processed to control a charging conversion module and an inversion conversion module. The independent photovoltaic power generation railway power supply control system has the advantages that the system adjusts, controls and outputs continuous and stable electric energy according railway load operation states and environmental conditions, electric energy quality and efficiency of photovoltaic power generation are increased, and the continuity and stability of power supply transmission are guaranteed.

Description

technical field [0001] The invention belongs to the technical field of railway power supply, and in particular relates to an independent photovoltaic power generation railway power supply control system and a control method thereof. Background technique [0002] The power supply of facilities along the railway is an important part of the railway operation and safety system. With the implementation of the national development strategy, the scope of railway operation is becoming wider and wider. When it is difficult to supply power in areas with weak power grids, it is urgent to solve the energy problem, and the investment in erecting the power grid is very high. However, my country is rich in solar energy resources, which are inexhaustible and inexhaustible. It is one of the fastest-growing energy sources in today's renewable energy sources, and it is also the focus of competing development in various countries. Vigorously develop solar energy resources for photovoltaic Power ...

AI Technical Summary

Problems solved by technology

[0003] There are equipment with special power requirements such as large impact loads and high stability loads of communication signals in railway electrical equipment, while solar photovoltaic power generation is greatly affected by the environment. In photovoltaic power generation systems, there are generally low solar conversion efficiency and low power supply system power. Insufficient problems not only waste clean energy and investment, but also pose a threat to the stability of the railway system
