Problems solved by technology

However, the accuracy of the total power generation difference method depends entirely on the value of the cumulative value of electricity at the start time and the cumulative value of electricity at the end time. When the value is abnormal or the total power generation of the wind power system returns to zero, the actual power generation cannot be accurately calculated.

Embodiment

[0023] Calculate the total power generation of the wind power system from 10:00:00 to 10:00:50, such as figure 1 shown in the steps to calculate,

[0024] 1) Data acquisition: start time 10:00:00 to end time 10:00:50, collect data every 5 seconds, and collect 10 power points in total.

[0025]

[0026] 2) Calculation of power accumulation difference:

[0027] 10:00:00-10:00:05, the difference is 0.5;

[0028] 10:00:05-10:00:10, the difference is 0.3;

[0029] 10:00:10-10:00:15, the difference is 0.0;

[0030] 10:00:15-10:00:20, the difference is 0.3;

[0031] 10:00:20-10:00:25, the difference is 3.9;

[0032] 10:00:25-10:00:30, the difference is 0.9;

[0033] 10:00:30-10:00:35, the difference is -3.0;

[0034] 10:00:35-10:00:40, the difference is 0.5;

[0035] 10:00:40-10:00:45, the difference is 1.4;

[0036] 10:00:40-10:00:45, the difference is 0.3;

Abstract

The invention relates to a calculation method of the power generation quantity of a wind power system, comprising the following steps: 1) performing data acquisition and data collection according to afixed period of time; 2) performing calculation of accumulated difference value of power quantity; 3) analyzing whether the accumulated difference value of power quantity is normal or not; if it is abnormal, replacing with corrected value; 4) summing up total power generation quantity from start time to end time. Preferably, the start time is 0 o'clock of the day and the end time is 24 o'clock ofthe day. Preferably, the fixed time period is 2 minutes 5 minutes. This algorithm can minimize the computational error even when the communication is interrupted and the data jumps abnormally in theprocess of data acquisition. The method is applicable to the calculation of wind power system power generation.

Description

technical field [0001] The invention relates to a calculation method of power generation, in particular to a calculation method of wind power system power generation. Background technique [0002] There are two methods to calculate the power generation of wind power system [0003] Method 1: active power integration method [0004] The existing wind power system can record the active power generation power of the wind power system at different times, and the total power generation of the wind power system within a certain time period can be calculated by integrating the active power generation power with the time period that needs to be measured. However, the accuracy of the active power integration method depends on the accuracy of the active power data and the continuity of the integration time. When the data acquisition of the wind power system is interrupted or the active power data is abnormal, the actual power generation cannot be accurately calculated; The active po...
