Description

This invention relates to an information processing system, an information processing method, and a program. In wind power generation systems, a technology for detecting failures in components on the power transmission line is known (Patent Document 1). Japanese Patent Publication No. 2013-170566 This figure shows an example of the overall configuration of an information processing system to which this embodiment is applied.This figure shows an example of the hardware configuration of the management server that constitutes the information processing system shown in Figure 1.This figure shows an example of the functional configuration of the control unit of the management server.This flowchart shows an example of the processing flow of the management server.This figure shows a specific example of the information displayed on the administrator terminal in Figure 1. Embodiments of the present invention will be described in detail below with reference to the attached drawings. <Configuration of the Information Processing System> Figure 1 shows an example of the overall configuration of the information processing system 1 to which this embodiment is applied. The information processing system 1 includes a management server 10, an administrator terminal 30, and power measuring devices 70-1 to 70-n (where n is an integer value of 1 or more). The management server 10 and the administrator terminal 30 are connected via a network 90. The network 90 is, for example, a LAN (Local Area Network), the Internet, etc. Hereinafter, unless it is necessary to explain each of the power measuring devices 70-1 to 70-n individually, they will be collectively referred to as "power measuring device 70". The administrator terminal 30 is connected to a power measuring device 70 installed for each wind turbine used in wind power generation (hereinafter simply referred to as "wind turbine"). [Management Server 10] The management server 10, which constitutes the information processing system 1, is an information processing device that acts as a server for managing the entire information processing system 1. The management server 10 is capable of executing application software that makes the information processing system 1 available for use. The management server 10 transmits various types of information to the administrator terminal 30 and external sources, and enables the execution of various processes. In addition, the management server 10 acquires various types of information transmitted from the administrator terminal 30 and external sources, and enables the execution of various processes. For example, the management server 10 acquires the measured power output from the wind turbine generator from the administrator terminal 30. Hereinafter, the measured power acquired by the management server 10 will be referred to as "measured output power." The measured output power acquired by the management server 10 is the same as the measured power measured by the power measuring device 70 (described later), and may be centrally managed by the administrator terminal 30. The management server 10 stores and manages the acquired measured output power in a database. The management server 10 calculates energy loss that reflects individual differences and operating conditions of the wind turbine, based on the initial value of the measured output power acquired before the wind turbine started operation and the cumulative value of the measured output power acquired and managed continuously after the wind turbine started operation. In this embodiment, energy loss is a value converted into electrical energy that represents the decrease in power generation efficiency that occurs over time or with continued operation, compared to the power generation efficiency when the wind turbine was installed and started operation (initial). Specifically, energy loss is a value derived by calculating the deviation between the measured output power at the time the wind turbine started operation (initial) and the cumulative value of the measured output power accumulated through continuous operation thereafter. Energy loss is an index that quantifies the decrease in energy conversion efficiency due to mechanical factors such as wear of wind turbine blades, increased friction of mechanical parts, and aging deterioration of the generator, as well as electrical factors such as resistance of electrical circuits and iron loss of magnetic circuits. Energy loss provides direct evidence for determining the degree of deterioration of the wind turbine. The management server 10 enables the calculation of such energy losses for predetermined periods, for each part of the wind turbine, for each wind speed element, and for each wind direction element. The management server 10 determines the degree of deterioration of the wind turbine based on the calculated energy loss. For example, the management server 10 may determine the degree of deterioration based on whether the calculated energy
