Also, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising … …" does not exclude the presence of other identical elements in a process, method, article, or apparatus that comprises the element.
As shown in fig. 1, fig. 1 is a flowchart illustrating a new energy station communication configuration method according to an embodiment of the present invention. The new energy station communication configuration method may include:
s101: communication points that need to be established in the data acquisition and supervisory control SCADA system are determined.
The communication point is a point in the new energy station which is communicated with the reactive voltage control device and the quick frequency response device.
S102: and establishing a communication point in the data acquisition and monitoring control system by adopting a communication point copying mode.
S103: and after the communication point is established, obtaining relevant information for drawing the comprehensive control interface of the new energy station.
S104: and drawing a comprehensive control interface corresponding to the new energy station according to the relevant information.
The new energy station provided by the embodiment of the invention comprises but is not limited to a wind power plant, a photovoltaic power station, a hydroelectric power plant and a thermal power plant.
For example, assuming that there are currently 20 communication points and that there are actually 34 communication points required, 14 communication points need to be established.
And establishing 14 communication points to be established in the SCADA system by adopting a communication point replication mode.
In an embodiment of the present invention, establishing a communication point in a SCADA system by using a communication point replication method may include: copying the current last communication point in the data acquisition and monitoring control system by adopting an incremental communication point copying mode; and modifying the copied communication point into a communication point to be established in the data acquisition and monitoring control system.
Before communication points are established in the SCADA system by adopting an incremental communication point replication mode, the incremental communication point replication mode needs to be configured.
The new energy station is taken as an example of a wind farm.
The incremental communication point replication method for the wind power plant is configured as follows:
[AddressOffset]
AIOCount＝9，AIO1＝1，AIO2＝1，AIO3＝1，AIO4＝1，AIO5＝2， AIO6＝2，AIO7＝2，AIO8＝2，AIO9＝2
DIOCount＝2，DIO1＝1，DIO2＝1
wherein, AddressOffset represents the offset of the address when the incremental communication point copies, AIOCount ═ 9 represents that the number of the digital quantity IO channels is 9, AIO1 ═ 2 represents that the address offset of the digital quantity channel 1 is 2; AIO2 ═ 1 indicates that the address offset for digital channel 2 is 1; AIO3 ═ 1 indicates that the address offset for digital channel 3 is 1; when AIO4 is 1, the address offset of digital channel 4 is 1; AIO5 ═ 1 indicates that the address offset for digital quantity channel 5 is 1; AIO6 ═ 2 indicates that the address offset for numeric channel 6 is 2; AIO7 ═ 2 indicates that the address offset for digital channel 7 is 2; AIO8 ═ 2 indicates that the address offset of digital quantity channel 8 is 2; AIO9 ═ 2 indicates that the address offset of digital quantity channel 9 is 2.
The number of the analog quantity IO channels is 2 when DIOCount is 2, and the address offset of the analog quantity IO channel 1 is 1 when DIO1 is 1; DIO2 being 2 indicates that the address offset of the analog IO channel 2 is 2.
And then storing a configuration file (assumed to be copynodcfg.ini) storing the incremental communication point copying mode configuration of the wind power generation system in a database of the engineering directory.
When an incremental communication point copying mode is adopted and a communication point is established in the SCADA system, the last communication point in the current database is selected, then a label corresponding to the incremental communication point copying mode is selected (assumed to be copying (customizing)), a configuration file configured by the incremental communication point copying mode is called, and the communication point is automatically established in the SCADA system.
Fig. 2a to fig. 2e are schematic diagrams illustrating a process of establishing a communication point by using an incremental communication point replication method according to an embodiment of the present invention.
From fig. 2a it can be seen that the current database name is: windture, there are 20 communication points in the current database, and the 20 communication points are respectively: WT0101, WT0102, … …, WT0119, and WT 0120. Wherein the last communication point is WT 0120. In addition, data corresponding to each point under the communication point WT0120, including roll names, descriptions and I/O connections, is also shown in fig. 2 a. The right key selects the last communication point WT0120 and shows the interface as shown in fig. 2 b. Clicking on the copy (customize) in fig. 2b, the interface shown in fig. 2c is displayed. The source communication point in figure 2c is copied at the area under the source communication point and the copied communication point is modified to a new communication point WT0121 to be established, as shown in the interface of figure 2 d. Exiting the interface shown in figure 2d shows the result of the establishment of the new communication point WT0121 as shown in figure 2 e.
As can be seen from figure 2e, in contrast to figure 2a, the communication point WT0121 is newly established and the points below the new communication point WT0121 are accompanied by data, without the user having to set up the data in the new communication point WT 0121. And the points below the new communication point WT0121 are incremented by the configuration file configured in the incremental communication point replication method.
According to the embodiment of the invention, the communication point is established by adopting an incremental communication point copying mode, a user does not need to set data in a new communication point, the error condition of manually adding the point is avoided, the communication configuration error of the new energy field station can be avoided, the debugging efficiency of the SCADA system can be improved, and the cost is saved.
In an embodiment of the present invention, establishing a communication point in a SCADA system by using a communication point replication method may include: copying the configuration information of the communication point, and modifying the copied configuration information of the communication point into configuration information corresponding to the communication point to be established; and establishing the communication point to be established in the data acquisition and monitoring control system according to the configuration information corresponding to the communication point to be established.
In one embodiment of the invention, the communication point configuration information may be stored in a configuration file for storing the communication point configuration information.
As an example, assume that the communication point configuration information of the profile record currently used for storing the communication point configuration information is as follows:
