施工电源规划能否满足施工用电要求,是保证工程顺利建设的重要条件。三峡工程施工主供电源由葛洲坝二江电厂220kV开关站隔出一回220kV线路至左岸陈家冲,建220kV变电所1座;备用电源为在右岸坝区附近断开葛旗220kV线路,建220kV变电所... 施工电源规划能否满足施工用电要求,是保证工程顺利建设的重要条件。三峡工程施工主供电源由葛洲坝二江电厂220kV开关站隔出一回220kV线路至左岸陈家冲,建220kV变电所1座;备用电源为在右岸坝区附近断开葛旗220kV线路,建220kV变电所一座,两者“π”接;左右岸交电所之间架设同杆双回220kV联络线;采用电力系统110kV电源作为保安电源。此方案提高了供电电源的可靠性,能较好满足最高用电负荷和施工进度的要求,并可节约投资,适应电力系统远景发展规划。 展开更多

The study presents possibilities for reconstruction of electric power supply systems in Bulgarian Black Sea resorts and possibilities to use statistical methods in energy planning. The paper shows the use of classic statistical methods in combination with advanced digital measurement systems in order to obtain the correlation dependencies, nature of energy consumption and opportunities for energy forecasting. The main purpose of the study is to obtain statistical dependencies of the nature of power consumption and correlations between electricity consumption and ambient temperature in order to improve the accuracy of energy planning. The analysis includes application of energy management systems for proper energy planning, improving economical efficiency and reducing power and energy losses. 展开更多
