The OTC receives all "PVC information" from the server using the REQ_PLIST packet, referring to the "number of connected PVCs" information received from the ACK_OLG packet. The server maintains a list of connected PVC information in the buffer and sends it to the OTC when it receives a request from the OTC. The OTC sets the search condition of the PVC to be displayed by using the option of REQ_PLIST, and sets the number of pieces of PVC information to be downloaded at one time. For example, if the number of currently connected PVCs is 100, 20 REQ_PLIST packets are sent to receive all 100 PVCs information. Currently, there is no restriction on the maximum number of PVC information to be received at a time in the "connection PVC list requesting procedure ". The number of PVC information in the SND_PLIST packet is the count value set in REQ_PLIST. Therefore, the number of PVC information is not defined separately in SND_PLIST. The OTC determines the color (green or red) of the PVC tile on the main screen by referring to the status information of the received PVC information and displays the status information of the selected PVC on the right side of the OTC main screen.

FIG. 13 is a flowchart illustrating a process for registering, modifying, and deleting an OTC operator of a remote interface apparatus of a photovoltaic power generation system according to an embodiment of the present invention.

The OTC operator registration shown in FIG. 13 (a) is possible only in the OTC, and the operator should be registered first when registering the new PVC. The operator's UID is automatically assigned by the server. When the "OK" button shown in FIG. 12 is clicked, the "operator registration procedure" is executed and the "operator management screen" is moved. On the other hand, if you click "Cancel" button, it goes to "Operator management screen".

After inputting the required information on the operator registration screen and clicking the "OK" button, a REQ_SMREG packet is sent to request the operator information to be newly registered. The "operator information" field not set in the input screen is set to "0".

The OTC operator modification shown in (b) of FIG. 13 executes the "operator modification procedure" when clicking the "OK" button on the modification screen and moves to the "operator management screen". On the other hand, if you click "Cancel" button, it goes to "Operator management screen". After entering the required information on the Modify Operator screen, click the "OK" button and the REQ_SMREG packet will be sent to request the modified operator information to the server. The registration request is reflected by reflecting only the modified part of the entire user information downloaded from the server.

The deletion of the operator shown in FIG. 13C is performed by selecting an operator on the operator management screen shown in FIG. 12 and then clicking on the "delete operator" button to request the server to delete the operator's UID through the REQ_SMDEL command.

The PVC management unit 530 may store information on PVC management such as PVC status, PVC sensing parameter setting, PVC registration, PVC inquiry, PVC fault diagnosis, etc. related to the PVC 150 connected to the solar power generation system 100 To be registered and managed in the database server 300. The status information of PVC contains information on the total number of registered PVCs and the number of PVCs connected to the current server. The PVC sensing parameter setting information includes a JOB sequence (a sequence of instructions to be executed in one sensing period), a sensing period (a repetition period for sensing the state of the solar power generation system), a sensing number (a repetition number of sensing cycles, And sends the sensing data to the server after sensing). The PVC sensing parameter setting can be set individually for each PVC or for each group to facilitate management.

Table 8 is an example table of packets relating to PVC registration, inquiry, and management of operator management packets of the OTC 500 according to an embodiment of the present invention.

FIG. 14 is a flowchart illustrating a process of registering PVCs in a remote interface apparatus of a photovoltaic power generation system according to an embodiment of the present invention.

The process of PVC registration will be described with reference to Table 8 and FIG.

First, enter the owner name on the PVC registration screen and click the "Confirm Registration" button to execute "User Registration Confirmation Procedure". When registering new PVC, "owner name" must be entered to check whether the owner is registered first. If the owner is unregistered, the owner's "user registration" must be performed first. In the PVC registration screen, the setting of the order of sensing commands is sequentially set up to ten using ',' (comma) as delimiter. For example, when command-2, command-5, and command-1 are executed in order, the order of sensing command is 2, 5, The sensing cycle represents the execution time (in seconds) of one "instruction sequence". The number of senses is calculated by executing the instruction sequence for the number of executions of the instruction sequence once, then taking the average value and transmitting it to the server. Main screen "when executing the" PVC registration procedure "by clicking the" OK "button after inputting the PVC registration information, while moving to the" main screen "when clicking the" cancel "button.

Then, in the PVC registration screen, the operator inputs "PVC registration information" into REQ_PREG and sends it to the server. The server automatically assigns a CID (Client ID) composed of a 4-byte serial number to the new PVC, sends it to the OTC in an ACK_PREG packet. The registration of the PVC 150 is registerable by owner or group.

15 is an exemplary view of a PVC search screen in an OTC of a remote interface device of a solar power generation system according to an embodiment of the present invention.

The inquiry of the registered PVC 150 can be inquired by using the CID of the PVC 150, the owner of the PVC 150, the status of the PVC 150 or the status of the PVC 150 as keywords. If not specified as search condition, '0' is sent. For example, if the owner real name is not specified, it sends '0' (1 byte).

FIG. 16 is a flowchart illustrating a process of searching PVC in the OTC of the remote interface apparatus of the solar power generation system according to an embodiment of the present invention.

The PVC search process will be described with reference to Table 8 and FIG.

The PVC search condition entered in the PVC search screen is loaded into FIND_PVC and transmitted to the server. PVC searches allow partial searches. Partial search uses keywords separated by a space character. For example, if you enter "Cheonan city Byeongcheon-myeon" at the installation location, the keywords are "Cheonan city" and "Byeongcheon-myeon", and search is "Cheonan city" AND "Byeongcheon-myeon". The server retrieves PVC information corresponding to the search condition, and sends the result (number of PVCs retrieved) to ACK_FIPV. The server maintains the search results, and is ready to send if the OTC requests REQ_PLIST. OTC sends the REQ_PLIST packet to the server for the number of retrieved results, and receives the PVC information in order. The method of requesting PVC information and the method of displaying on the screen shall be decided by OTC.

FIG. 17 is a flowchart illustrating a process of modifying and deleting PVC in an OTC of a remote interface device of a solar power generation system according to an embodiment of the present invention.

In the modification of the PVC shown in FIG. 17A, the setting of the sensing command sequence in the PVC modification screen is sequentially set up to ten using ',' (comma) as a delimiter. For example, when command-2, command-5, and command-1 are executed in order, the order of sensing command is 2, 5, The sensing cycle represents the execution time (in seconds) of one "instruction sequence". The number of senses is calculated by executing the instruction sequence for the number of executions of the instruction sequence once, then taking the average value and transmitting it to the server. If you click the "OK" button after inputting the above-mentioned PVC correction information, it executes the "PVC modification procedure" and moves to the "main screen".

The PVC information input from the PVC modification screen is loaded into the MOD_PVC packet and sent to the server to request modification. The OTC receives the ACK_MOPV packet and confirms "fix successful", updates the PVC information stored in the local buffer of the main screen, and updates the contents displayed on the screen as necessary.

The deletion of the PVC shown in FIG. 17B is carried out by sending the CID of the PVC selected in the PVC search screen of FIG. 15 to the DEL_PVC packet to request deletion. When the OTC receives the ACK_DEPV packet and confirms "Successful deletion", it deletes the PVC information stored in the local buffer of the main screen and deletes the contents displayed on the screen if necessary.

The PVC management unit 530 can set the method of notifying the OTC 500 of the operator or the UTC 400 of the user when the failure of the PVC 150 occurs and can set the failure parameters to be monitored (for example, the overvoltage limit value setting, Setting, overheating, etc.) can be set in individual PVC or PVC group units.

The user management unit 540 informs the database server 300 of information on the user's name, address, contact information, and the user's own photovoltaic power generation system through the UTC server on the basis of information about the user who is the owner of the photovoltaic power generation system To be registered.

Table 9 is an exemplary table of packets relating to user registration and management of an operator management packet of the OTC 500 according to an embodiment of the present invention.

Figure 112015074427790-pat00009

18 is a flowchart showing a user registration and a registration confirmation process in the OTC of the remote interface apparatus of the solar power generation system according to an embodiment of the present invention.

The user registration and registration confirmation process will be described with reference to Table 9 and FIG.

The user registration process shown in FIG. 18A requests the user to register a new user by sending a REQ_UREG packet when the user clicks the "OK" button after inputting necessary information on the user registration screen. Of the user information fields, fields not input on the user registration screen are processed as '0'. The OTC receives the UID assigned to the user after completion of registration through ACK_UREG.

In the user registration confirmation process shown in FIG. 18 (b), when the operator inputs the owner real name in the owner (user) information box in the PVC registration process of FIG. 14 and then clicks the "registration confirmation" button, the CHK_UREG packet is sent The server confirms whether or not the user is registered. If the user is registered, the registered user information is sent. If the user is not registered, '0' is sent. If the user is a registered user, the PVC registration process is continued. In the case of an unregistered user, after executing the "user registration process ", the PVC registration process is continued.

The OTC display unit 550 displays an OTC registration screen, an OTC login screen, an operator management screen, a user management screen, a PVC management screen such as registration and connection status of PVC, status information of the PV system, environmental information, Information, or a combination thereof, or an OTC setting screen, can be remotely monitored in real time.

FIG. 19 is a view showing an OTC main screen of a remote interface apparatus of a photovoltaic power generation system according to an embodiment of the present invention.

Button to go to "PVC search screen" and click "System setting" button to go to "System setting screen".

The "PVC tile map" on the left side of Fig. 19 represents the PVC currently connected to the server. This connection status should be updated in real time. Currently, even if a new PVC is connected to the server or the state of the connected PVC changes, the server does not notify the OTC but updates only the PVC database value. Therefore, the OTC periodically sends a REQ_QLIST packet (setting the appropriate option) to the server to update the "PVC tile map" in real time. The update period of the "PVC tile map" is set in "System configuration".

Clicking the button at the bottom generates a "button click event" and this event occurs asynchronously. OTC can be used to repeatedly execute the "PVC Connection Status" updater event that sends a REQ_QLIST packet to the server and the "button click event handling request packet" of the main screen, or to synchronize the "PVC Connection Status" update event and the asynchronous button In order to process events, an event queue is defined and an event handler for processing the event queue is implemented and can be sequentially executed repeatedly.

As described above, the present invention relates to a remote interface apparatus and method for a photovoltaic power generation system. In order to efficiently manage a photovoltaic power generation system, a photovoltaic power generation system management server pool is constructed, It is easy and convenient to inquire and manage information about the state of the PV system, environmental measurement information, or a combination of them through the PC of the operator who manages and operates the photovoltaic system or the portable terminal of the user who is the owner of the PV system It is possible to more conveniently manage and operate the photovoltaic power generation system by the operator or the user.
