Embodiment Construction
[0025] The following examples are only used to illustrate the technical solutions of the present invention more clearly, and cannot be used to limit the protection scope of the present invention.
[0026] An active peak clipping and loss reduction method based on voltage control, real-time acquisition and monitoring of feeder, distribution transformer and user terminal voltage, analysis of feeder operation status, estimating the adjustable range of all controllable equipment and the reduction of all controllable equipment. capacity, when the feeder is in peak period, the main power distribution station uses the voltage control algorithm to realize the voltage regulation of all controllable equipment, reduce the voltage of all controllable equipment to cut peak and reduce losses, and maintain the voltage of all controllable equipment at the same time. within the standard range.
[0027] Further, estimating the adjustable range of all controllable devices and the capacity that a...

The invention discloses an active peak shaving and loss reduction method based on voltage control. Based on the distribution network automation system, various terminal units installed in the distribution network are used to collect and monitor the voltage of 10kv feeders, distribution transformers and user terminals in real time. Analyze the operating status of the feeder. When the feeder is at its peak, the main power distribution station uses the voltage control algorithm to adjust the voltage of the transformer tap, capacitor, and line voltage regulator, thereby reducing the voltage to cut the peak and reduce the loss. At the same time, the voltage Stay within the standard range. On the premise of not changing the grid structure, through the established power distribution automation system, the voltage control function is used to reduce the load terminal voltage, and at the same time keep the load terminal voltage within its required working range, thereby reducing the load terminal power and achieving reduction The purpose of peak loss reduction.
Description
technical field [0001] The invention relates to an active peak clipping and loss reduction method based on voltage control, and belongs to the technical field of electric power grids. Background technique [0002] With the development of society and economy, reliable power supply services have become the top priority of power companies and customers, especially during peak loads, how to reduce the impact of peak power cuts or unexpected events on the power grid, and ensure reliable power supply capacity and sufficient power supply capacity, It has become a huge challenge faced by power companies. The existing peak shaving management has the following problems: [0003] 1. Power curtailment, due to insufficient system capacity, needs to be avoided by means of power curtailment. [0004] 2. Increase the spare capacity of the system, resulting in excessive investment and high light load loss. [0005] 3. Overload and heavy load reduce the service life of the equipment. SUMM...
