WIND TURBINE MAINTENANCE OPTIMIZER
First Claim
1. A method of scheduling maintenance tasks in a power plant, comprising:
- generating, based on a plurality of inputs, respective net present values associated with performing maintenance on two components in the power plant, wherein at least one of the plurality of inputs is a value that predicts at least one of;
a future performance of the two components and a future price of electrical power;
determining a priority between the two components based on at least in part the respective net present values; and
generating, based on the determined priority, a maintenance schedule for performing a preventative maintenance task on at least one of the two components.

Abstract
Determining when to perform preventative maintenance is an important consideration for maximizing the revenue of a wind turbine. For example, performing preventative maintenance may be cheaper than replacing turbine components when they fail. When determining to perform preventative maintenance, a maintenance scheduler may consider multiple factors. These factors may include the probability of failure, the predicted price of energy, predicted wind power production, resource constraints, and the like. Specifically, the maintenance scheduler may predict the future values of these factors which are then integrated into a net present value (NPV) for each of the components. Based on the respective NPVs, the maintenance scheduler may determine which maintenance actions to perform and in what order.
