Embodiment Construction
[0050] The invention relates to a method for calculating energy saving in energy efficiency improvement and transformation of intelligent substations. This method starts from the energy efficiency improvement and transformation measures of smart substations, and calculates and deduces the energy efficiency of smart substations by calculating and deriving the energy saving of power transformer transformation, power saving of station power transformation, and electricity generated by new energy access in the process of energy efficiency improvement and transformation of smart substations. Improve the energy saving of transformation. This method is novel in theory. Compared with traditional substation energy efficiency improvement and transformation, the electricity saved by new energy access is included in the substation energy saving. A new way of thinking and method. The invention helps power grid enterprises to accurately grasp the power saving situation of energy efficiency...

The present invention provides an intelligent substation energy efficiency enhancement transformation energy saving amount calculation method which mainly comprises the steps of (S1) according to intelligent substation energy efficiency enhancement transformation information, determining and detecting substation each parameter, (S2) calculating the transformer power saving total amount of intelligent substation energy efficiency enhancement transformation, (S3) calculating station power saving amount of the intelligent substation energy efficiency enhancement transformation, (S4) calculating the power amount generated by new renewable energy equipment of the intelligent substation energy efficiency enhancement transformation, and (S5) calculating the power saving amount of the intelligent substation energy efficiency enhancement transformation according to an intelligent substation operation condition. Through analyzing the main power equipment power saving amount of the intelligent substation energy efficiency enhancement transformation, a station power saving amount condition and the power amount generated by the renewable energy, the intelligent substation power energy saving amount can be effectively obtained.
Description
technical field [0001] The invention belongs to the field of electric power systems, and in particular relates to a method for calculating energy saving in energy efficiency improvement and transformation of intelligent substations. Background technique [0002] In the power system, the power of the grid is delivered to users through links such as power transmission, power transformation and power distribution. Substations play the role of power distribution in the power system. Smart substation adopts advanced, reliable, integrated and environment-friendly intelligent equipment, with the basic requirements of digitalization of whole station information, networking of communication platform, and standardization of information sharing, and automatically completes basic functions such as information collection, measurement, control, protection, measurement and detection. At the same time, it is a substation with advanced functions such as real-time automatic control of the po...
