家用光伏发电系统设计
摘要：能源是国民经济发展和人民生活水平提高的重要物质基础。世界范围内的能源短缺和环境污染已成为制约人类社会可持续发展的两大重要因素，大力发展新的可替代能源已成为当务之急。随着经济的发展，社会的进步，电能的消耗越来越大，传统的火电需要燃烧煤、石油等化石燃料，一方面化石燃料蕴藏量有限、越来越少，正面临着枯竭的危险，另一方面燃烧将排出二氧化碳和硫的氧化物，因此会导致温室效应和酸雨，恶化地球环境，太阳能发电作为一种新的电能生产方式，以其无污染、无噪音、维护简单等特点显示出无比广阔的发展空间和应用前景。太阳能是一种干净的可再生的新能源，越来越受到人们的亲睐。光伏并网发电作为太阳能发电的主要形式之一，也越来越受到关注。因此深入研究光伏并网发电系统，对于缓解能源危机、保护环境、维护社会稳定、促进经济的可持续发展等都具有深远而重大的理论和现实意义。在并网型发电站中电气设计最为关键，其设计的合理性、安全性将影响着整个电站的取得电能、分配、输送与保护等功能，合理、安全的电气控制设计才能保证将电能安全、可靠、经济的输送到每个用电设备的转设场所。

Grid type photovoltaic power plant electrical design
Abstract：Energy is the national economic development and people's living standards improve the important material base. Worldwide energy shortage and environmental pollution have become two most important factors for the sustainable development of human society, vigorously develop new alternative energy has become the urgent matter. Along with the development of the economy, the progress of the society, the consumption of electrical energy is more and more big, the traditional thermal power need to burn fossil fuels such as coal, oil, less fossil fuel reserves is limited, on one hand, is in danger of drying up, on the other hand burns will emit carbon dioxide and sulfur oxide, thus causes the greenhouse effect and acid rain, deterioration in the earth's environment, solar power as a new way of electric energy production, with no pollution, no noise, simple maintenance and so on showed a very broad space for development and application prospect. Solar energy is a new clean and renewable energy, more and more get the favor of people. Photovoltaic (pv) grid power generation as one of the main form of solar power, is becoming more and more attention. So further study of photovoltaic (pv) grid power generation system, to relieve the energy crisis, environmental protection, maintain social stability, promote the sustainable development of economy and so on all has profound and significant theoretical and practical significance. Electrical design is the most crucial in the grid type power station, the rationality of the design and security will affect the whole plant, distribution, transmission, and protection of electric power, and other functions, reasonable, safe electrical design in order to ensure the safety of electricity, reliable and economical to each to a place of electrical equipment.
Keywords: Solar energy; Solar power; Photovoltaic (pv) grid power generation; Electrical design
