Wind reduction calculation formula

Introduction The calculation formula for wind power reduction is as follows: wind power reduction = theoretical grid power of all wind farms during the power limitation period - actual grid power of all wind farms during the period power limitation. Among them: the co

Wind reduction calculation formula

The formula for calculating abandoned wind power is: Abandoned wind power = Theoretical grid-connected power of all wind farms during the power limitation period - The actual grid-connected power of all wind farms during the power limit. period.

Among them:

Theoretical grid power of the entire wind farm = ∑ Wind power generation model ÷ (Capacity of the model wind turbine/ operating capacity of the wind farm) - Wind loss of internal transmission line of the wind farm - Electricity consumption of the installation

The actual energy production of the entire wind farm = the statement of meter of the wind farm access network interface. The power restriction period is determined by the electricity distribution agency.

The number of wind farm prototypes must not exceed 10% of the total number of wind turbines on sitee. The determination of wind farm prototypes is, in principle, appointed by the electricity dispatch agency and is evenly distributed according to geographical location and terrain, taking into account micro-wind conditions, taking full account takes into account units of different types and capacities, and determined based on exhaustive methods, genetic algorithms, etc. The reference wind turbine combination strives to accurately reflect the actual overall power generation capacity of the wind farm.

The difference in the size of the overall wind farm reduction coefficient

The precise algorithm for equivalent hours is: the number of operating hours calculated by dividing the amount of electricity production during the reporting period by the capacity of the electricity generation equipment. Equivalent hours are an important indicator for measuring production performance ofelectricity for a project. In simple terms, it is the ratio of annual electricity production to capacity. For a single unit, it is the ratio between the annual electricity production of the single unit and the capacity of the unit and for a wind farm, it is the ratio between the annual electricity production of the entire site and the installed capacity of the entire site; .

The theoretical energy production calculated by the wind power software should be modified as follows depending on the degree of influencing factors.

1) Air density reduction, the calculation formula of air density reduction coefficient is: air density reduction coefficient = (1 - wind field air density / standard air density) * before the rated wind speed Wind energy frequency.

If the on-site air density power curve is used to calculate electricity productionity, it is not necessary to reduce it.

2) Reduction of wake losses The wake losses of each wind turbine are generally taken into account by software calculations, so the reductions will not be repeated.

3) The utilization rate of wind turbines depends on whether the wind turbines are out of service or repaired, then on the grid.

Organize Tangfeng Songxiu in Xiaofengyue. Based on the current manufacturing level of wind turbines and the actual situation of the wind farm, the utilization rate of wind turbines is estimated to be around 95%.
