Data management systems and methods
This disclosure related to systems and methods that facilitate the secure collection and management of operational data relating to a power generation system that includes one or more wind turbines. Embodiments disclosed herein may also be used to provide various insights on wind farm operation and management using collected operational data. Further embodiments facilitate policy-managed access to operational data, including policy-managed access implementing differential privacy, in a manner allowed and/or otherwise controlled by parties having ownership rights or interests in the data.
1. A method for managing operational data associated with power generation equipment performed by a trusted service system comprising a processor and a non-transitory computer-readable medium storing instructions that, when executed by the processor, cause the trusted service system to perform the method, the method comprising:
receiving, from a data analysis program, a request to access a set of operational data, the request comprising a first digital signature;
identifying a policy associated with the set of operational data, the policy articulating at least one first condition for accessing the set of operational data, the at least one first condition being associated with the first digital signature, the at least one first condition comprising applying a transformation to the set of operational data using information provided by a data transformation service;
generating based, at least in part, on the at least one first condition articulated by the policy, a transformation information request;
transmitting the transformation information request to the data transformation service;
receiving, in response to the transformation information request, transformation information from the data transformation service;
generating a response to the request to access the set of operational data based, at least in part, on the policy and the transformation information received from the data transformation service; and
transmitting the response to the data analysis program.
2. The method of claim 1 , wherein the policy is securely associated with the set of operational data.
3. The method of claim 1 , wherein identifying the policy comprises identifying the policy in a policy manifest securely associated with the set of operational data.
4. The method of claim 1 , wherein the data analysis program is executed on the trusted service.
5. The method of claim 1 , wherein the data analysis program is executed on a user system separate from the trusted service system.
6. The method of claim 1 , wherein the set of operational data comprises operational data associated with one or more wind turbine systems.
7. The method of claim 1 , wherein the set of operational data comprises operational data associated with one or more solar power generation systems.
8. The method of claim 1 , wherein generating the response to the request to access the set of operational data comprises:
applying the transformation to the set of operational data using the transformation information received from the data transformation service.
9. The method of claim 8 , wherein the transformation comprises adding noise to the set of operational data.
10. The method of claim 9 , wherein the transformation information received from the data transformation service comprises noise information.
11. The method of claim 1 , wherein the transformation information request comprises a second digital signature associated with the trusted service system.
12. The method of claim 1 , wherein the transformation information received from the data transformation service further comprises a third digital signature associated with the data transformation service.
13. The method of claim 12 , wherein the at least one first condition comprises applying a transformation to the set of operational data using information that comprises the third digital signature.
14. The method of claim 13 , wherein generating the response to the request to access the set of operational data comprises verifying the third digital signature.
15. The method of claim 1 , wherein the policy further articulates at least one second condition for accessing the set of operational data, the at least one second condition comprising recording audited access information relating to access to the set of operational data.
16. The method of claim 1 , wherein the method further comprises generating, in response to transmitting the response to data analysis program, audited access information relating to the access to the set of operational data by the data analysis program.
17. The method of claim 16 , wherein the method further comprises transmitting the audited access information to an auditing system.
18. The method of claim 1 , wherein the method further comprises verifying the first digital signature.
