Off Grid Solar System Distributed Power Generation System Jun 21, 2017

Off Grid Solar System Distributed power generation system

Distributed photovoltaic power generation refers specifically to the use of photovoltaic modules, the direct conversion of solar energy into a distributed power generation system. It is a new type, with broad prospects for the development of comprehensive power generation and energy use, it advocates the nearest power generation, near the grid, the nearest conversion, the nearest use of the principle, not only can effectively improve the same size photovoltaic power generation capacity, Effectively solve the power in the boost and long-distance transport in the loss of the problem.

Distributed photovoltaic power generation system, also known as decentralized power generation or distributed energy supply, refers to the user site or near the electricity site configuration of the smaller photovoltaic power supply system to meet the needs of specific users to support the existing distribution network economy Run, or at the same time meet these two requirements.

The basic equipment of the distributed photovoltaic power generation system includes the components of the photovoltaic cell, the PV array bracket, the DC converter box, the DC power distribution cabinet, the grid inverter, the AC power distribution cabinet and so on. In addition, the power supply system monitoring device and the environmental monitoring Device. Its operating mode is in the solar radiation conditions, the photovoltaic power generation system, the array of solar cells will be converted to solar energy output, through the DC bus box into the DC power distribution cabinet, by the grid inverter inverter AC power supply The building itself loads, excess or insufficient power is regulated by connecting the grid.

Distributed photovoltaic power generation system Applications: in rural areas, pastoral areas, mountains, the development of large, medium and small cities or commercial areas near the construction, to solve the local user needs.

The State Energy Bureau promulgated the Interim Measures for the Management of Distributed Photovoltaic Power Generation Projects on November 18, 2013, and provided investment and construction of distributed photovoltaic power generation projects for various types of power users, investment enterprises, specialized contract energy service companies and individuals The government guiding principles, the text reads as follows:

Interim Measures for the Administration of Distributed Photovoltaic Power Generation Projects

Chapter 1 General Provisions

Article 1 In order to standardize the construction and management of distributed photovoltaic power generation projects and promote the application of distributed photovoltaic power generation, according to the Renewable Energy Law of the People's Republic of China, the Electricity Law of the People's Republic of China, the Administrative Licensing Law of the People's Republic of China, The State Council on the promotion of the healthy development of photovoltaic industry a number of opinions ", the development of this approach.

The second distributed photovoltaic power generation is in the user's site or near the construction and operation to the user side of the spontaneous self-use, the excess power of the Internet and in the distribution system balance characteristics of the photovoltaic power generation facilities.

Article 3 Encourage all kinds of electric power users, investment enterprises, specialized contract energy service companies, individuals, etc. as a project unit to invest in the construction and operation of distributed photovoltaic power generation projects.

Article 4 The competent department of energy under the State Council shall be responsible for the planning and supervision and management of distributed photovoltaic power generation in the whole country. The local competent department of energy under the guidance of the competent department of energy under the State Council shall be responsible for the supervision and administration of distributed photovoltaic power generation planning and construction in the region. Responsible for the region's distributed photovoltaic power generation planning and policy implementation, and network operation, market fairness and operational safety supervision.
