Detailed Description
Reference will now be made in detail to embodiments of the present application, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar modules or modules having the same or similar functionality throughout. The embodiments described below with reference to the drawings are exemplary only for the purpose of explaining the present application and are not to be construed as limiting the present application. On the contrary, the embodiments of the application include all changes, modifications and equivalents coming within the spirit and terms of the claims appended hereto.
Example 1
In order to prevent the accumulated power generation data from being manually recorded or even lost due to an accident in the life cycle of the wind turbine generator system, the embodiment specifically provides an automatic connection method for the accumulated power generation in the wind turbine generator system, and when the automatic connection method is implemented, the required devices include: the system comprises an electric quantity acquisition module of the wind generating set, a master control system and a central monitoring system. According to the method, according to two criteria, firstly, the accumulated power generation amount of the wind generating set is increased in a single-side mode, and an increment upper limit is arranged in a certain period; and secondly, the accumulated generated energy of the wind generating sets stored in the central monitoring system of the wind power plant is persistent and consistent.
When the wind generating set normally operates, the master control system can periodically collect the accumulated generated energy calculated by the electric energy collection module, the reasonability of the collected electric energy is checked according to the single-side increment and 120% full-rated output increasable electric energy in the period on the accumulated generated energy data, wherein 120% is a settable parameter and is set according to the actual capacity of the wind generating set.
During normal operation, a central monitoring system of the wind power plant can periodically collect accumulated generated energy data of a main control system in the wind generating set, the reasonability of the collected electric quantity is checked according to unilateral incremental and 120% full-rated output increasable electric quantity in a period, wherein 120% is a settable parameter and is set according to the actual capacity of the wind generating set.
As shown in fig. 1, the automatic continuing method for accumulating the power generation amount in the wind turbine generator system, when actually applied, should include:
s1: when the electric quantity acquisition module of the wind generating set is replaced, during the running period of a main control system of the wind generating set, the main control system automatically calculates the offset generated by replacing the electric quantity acquisition module according to a set rule;
when the electric quantity acquisition module of the wind generating set is replaced, the set rule of the master control system is as follows:
a1: setting the accumulated generated energy as Gc, wherein the accumulated generated energy Gc is the accumulated electric quantity data value recorded by the read file when the system starts to run; setting an offset T, wherein the offset T is an offset value for reading file records and also records data for files in the wind generating set; t1 is the time of reading from the file, and is the time corresponding to the Gc data;
setting Gc2 as the cumulative power generation amount of the current cycle, and assigning initial values to Gc2, for example: assigning Gc2 a value of-1;
gc1 is set as the accumulated power generation amount of the previous cycle.
A2: reading the accumulated generating capacity Gd of the current time t from the electric quantity acquisition module;
a3: the cumulative power generation amount Gc 'at the current time T is calculated as Gd + T, and if the offset T is correct, the cumulative power generation amount after update is calculated by the formula, where "assigning" means assigning a value of Gd + T to the cumulative power generation amount Gc, and for easy understanding, assigning the cumulative power generation amount at the current time T as Gc' to the cumulative power generation amount Gc 'to indicate the updated cumulative power generation amount Gc' after assigning the cumulative power generation amount Gc.
A301: judging whether the master control system reads the accumulated generated energy data of the electric quantity acquisition module for the first time, and if so, executing A302; if not, executing A303;
a302: the accumulated power generation amount data is read for the first time, then, in this case, the accumulated power generation amount of the last cycle should be the recorded accumulated power generation amount, and therefore Gc is assigned to Gc 1; meanwhile, according to the calculated accumulated power generation Gc ', the accumulated power generation in the current period is required, so that the Gc' is assigned to Gc2, the current period is t-t1 (the current time t minus the time t1 for reading the file record), and Gxc is the maximum possible power generation of the wind generating set in the current period according to the design;
a303: gc2 is assigned to Gc1, Gc' is assigned to Gc2, and Gxc is the maximum possible power generation of the wind generating set in the current period according to the design. In this case, the accumulated power generation amount data is not read for the first time, and for example: is the second-read accumulated power generation amount data, then, at this time, the accumulated power generation amount of the previous cycle should be the "accumulated power generation amount data of the current cycle" in the above-described step a302, and therefore, it is necessary to assign Gc2 to Gc1, and, at the same time, in this case, the accumulated power generation amount Gc' of the current time should be assigned to Gc2 to obtain Gc2 updated for the current cycle. The term "assignment" is understood to mean "update".
A4: judging whether Gc2-Gc1> is 0 and Gc2-Gc1< (Gxc) is true, if true, updating the accumulated power generation Gc recorded by the file in the wind generating set by using Gc2, and updating the recording time in the wind generating set; the principle of this section is as follows: if the current period is the same as the previous period, the acquired data of the previous period is proved to be smaller than the acquired data of the current period, the electric quantity of the electric quantity acquisition module does not jump, the electric quantity acquisition module is not replaced, and the electric quantity acquisition module continuously acquires data all the time, so that the data under the condition is real and effective, and the accumulated generated energy Gc is directly updated.
If the current accumulated generated energy is not Gc ═ Gd + T ', the electric quantity of the electric quantity acquisition module jumps, the Gc1, the Gc2 and the current time T are recorded into an error log, the offset T ═ Gc1-Gd is recalculated, the recorded offset T ' is updated, and the current accumulated generated energy is calculated to be Gc ═ Gd + T '. The principle of this section is as follows: if the electric quantity collection module is replaced, the accumulated electric quantity data calculated by the electric quantity collection module starts from 0 again, the data collected in the current period is 0, and the data collected last time is far more than 0, so that the Gcc (Gcc is Gc2-Gc1) is less than 0 and does not meet the condition, and further the electric quantity is judged to jump, and then Gc2, Gc1, T and the current time are all written into error logs so as to record the occurrence of data error events generated by the replacement of the electric quantity collection module.
S2: when a master control system of the wind generating set is replaced or a file stored in the master control system is lost, during the running period of a central monitoring system of the wind generating set, the central monitoring system automatically calculates the offset generated by the master control system according to a set rule;
when a master control system of the wind generating set is replaced or a file stored in the master control system is lost during the operation of a central monitoring system of the wind generating set, the operation rules set by the central monitoring system are as follows:
b1: reading the accumulated generated energy Gm of the wind generating set stored in the database of the central monitoring system and recording the time t1 of the accumulated generated energy Gm by the central monitoring system; acquiring the accumulated generated energy Gc of the master control system currently, wherein the current acquisition time is t;
b2: setting Gm1 as last data collected in the master control system, and Gm2 as current data collected in the master control system;
b201: judging whether the central monitoring system collects the accumulated generated energy data of the master control system for the first time, if so, executing the step B202; if not, executing step B203;
b202: in this case, since data is collected in the master control system for the first time, the data on the upper time adopts the accumulated power generation data stored in the database, and then the Gm is assigned to the Gm 1; of course, the accumulated power generation Gc collected at the current time should be the current data, therefore, Gc is assigned to Gm2, and the current collection period is the current time t minus the time t1 read from the database, Gxm is the maximum possible power generation of the wind generating set in the current period according to the design. In the above, the cumulative power generation amount Gm at the time t1 is assigned to the Gm1 as the previous collected data, and the cumulative power generation amount Gc at the time t is assigned to the Gm2 as the current collected data; wherein Gxm can be set as rated power multiplied by t-t1 multiplied by 120%, and 120% is determined according to actual over-sending capacity of the unit.
B203: gm2 is assigned to Gm1, Gc is assigned to Gm2, and Gxm is the maximum possible power generation of the wind generating set according to the design period. In this case, if the accumulated power generation data of the master control system is collected for the first time, the stored accumulated power generation Gm is used as the last data, and the accumulated power generation Gc of the master control system is currently collected as the current data; if the accumulated power generation amount data of the master control system is collected for the second time, taking the current data (Gm2) in the first time (last time) as the last data (Gm1) and assigning a value to Gm1 by Gm2 for the second time; and taking the accumulated power generation Gc of the master control system acquired at the current time as current data, and assigning a value to Gm2 by the Gc.
B3: and judging whether the Gm2-Gm1> is 0 and the Gm2-Gm1< (Gxm) is true, if so, determining that the data are valid, and storing the data and the time into a database. The principle is as follows:
if the accumulated electricity quantity data of the master control system is not established, the accumulated electricity quantity data of the master control system is considered to have jump, the Gm1 is sent to the master control system (the Gm1 is rewritten to the master control system through the central monitoring system), and Gm1, Gm2 and the current time are written into an error log. The principle is as follows: after the main controller is replaced, the original stored deviant and the accumulated generated power value are lost, so that the accumulated generated power quantity is suddenly reduced, wherein Gmc is less than 0(Gmc is Gm2-Gm1), meanwhile, the main control system causes file confusion due to accidental power failure, the original deviant and the accumulated generated power value are changed into large values, and Gmc is greater than Gxm. In this case, it is determined that the accumulated power generation amount data of the master control system has jumped. And writing the Gm2, the Gm1 and the current time into an error log so as to record the jump event of the accumulated power generation amount of the master control system.
B4: after the master control system receives the Gm1, the Gm1 is used as accumulated generated power, the accumulated generated power is subtracted from the electric quantity data Gd read by the master control system from the electric quantity acquisition module, the offset T ' is recalculated to be Gm1-Gd, the recorded offset value T ' is updated, and the Gm1, the T ' and the current time are written into a file record.
S3: if the offset is accurate and effective, the offset is superposed into the electric quantity data acquired by the electric quantity acquisition module, and the current accumulated electric quantity is calculated; and if the updated offset value T' is recalculated, the updated offset value is superposed to the electric quantity data acquired by the electric quantity acquisition module, and the current accumulated electric quantity is calculated.
