Method, configuration, use of the method and computer program product for evaluating energy engineering data

Abstract

A method evaluates power engineering data using a data request that is transmitted to a coupling device by a first communication link. The coupling device is used to convert the data request from a coupling data format into a further data request that is specific to an energy engineering device in a device-specific data format. The further data request is transmitted to the power engineering device by a second communication link. The power engineering device transmits its power engineering data, requested by the further data request, to the coupling device by the second communication link. The power engineering data are in a data format that is specific to the power engineering device, and the coupling device converts all the power engineering data requested by further data requests into a data response in the coupling data format and uses the first communication link to transmit them to the evaluation device.

Description

BRIEF DESCRIPTION OF THE DRAWING

(1) The single FIGURE of the drawing is an illustration of all the components that are present for a provider of evaluation solutions according to the invention.

DETAILED DESCRIPTION OF THE INVENTION

(2) Referring now to the single FIGURE of the drawing in detail thereof, there is shown in an upper area of the FIGURE all the components that are present for a provider of evaluation solutions, for example. The upper area is therefore a provider area 50. The provider area 50 contains an evaluation arrangement 2 having evaluation devices 41-44.

(3) All the components that are used for communication are shown in a central area. The central area 52 is therefore a communication area 52 and shows first communication links 4, which are transmitted via the Internet 51. The first communication links 4 have end-to-end encryption in this case.

(4) All the components that are in place with a customer of the provider of evaluation solutions are shown in a lower area. The lower area is therefore a customer area 53. The customer area 53 contains a coupling device 5 to which energy engineering devices 11-15 are connected by second communication links 21, which are in the form of cable connections for Ethernet, for example. In addition, the customer area 53 contains a display device 30 by which a user at the customer end can use the evaluation arrangement 2.

(5) The manner in which the method according to the invention works will be explained below.

(6) A user uses the display device 30, for example, to initiate activation of the two evaluation devices 41 and 42; in this case, the evaluation device 41 is a load forecast device and the evaluation device 42 is a grid stability computation device. The two evaluation devices 41, 42 require energy engineering data for their evaluation and therefore contribute to producing a data request 3 within the evaluation arrangement 2.

(7) The data request 3 contains queries pertaining to the required energy engineering data. The data request 3 is produced in a coupling data format and its data format is therefore independent of the data format that is used in the respective evaluation device 41 or 42. The data request 3 is transmitted to the coupling device 5 via the Internet 51 in encrypted form by the first communication link 4.

(8) Within the coupling device 5, the data request 3 is converted into at least one data request 6-10, that is specific to an energy engineering device 11-15 in a device-specific data format. This means that the specific data requests 6-10 are now available specifically in the respective data format of the energy engineering device 11-15 that is to be interrogated, and can be transmitted to the energy engineering device directly by the second communication link 21.

(9) Within the energy engineering devices 11-15, the specific data requests 6-10 are each used to provide the requested energy engineering data 16-20. The energy engineering data 16-20 are transmitted back to the coupling device 5 via the second communication link 21.

(10) Within the coupling device 5, the energy engineering data 16-20 that are available in the respective data format of the energy engineering devices 11-15 are combined in a single data response 22 in the coupling data format. The data response 22 is then transmitted back to the evaluation arrangement 2 via the Internet 51 by the first communication link 4.

(11) In the evaluation arrangement 2, the data response 22 is conditioned such that the requested energy engineering data are provided therefrom for the evaluation device 41 and for the evaluation device 42 in the respective data format required by the evaluation device 41, 42.

(12) It is an essential advantage of the presented method according to the invention that once the coupling device 5 has been set up in the customer area 53 no further alterations need to be made in the customer area 53, even if the evaluation arrangement 2 in the provider area 50 is altered such that altered or other evaluation devices 41-44 are used; this is true even if totally different data formats than previously are required for these altered or new evaluation devices 41-44.

(13) In this way, constant improvement and adjustment of the evaluation arrangement can take place at the provider end without adjustments being necessary at the customer end. This is advantageous particularly with regard to security aspects and modernization of evaluation devices 41, 42.
