Abstract: In operation control for a femto base station apparatus, file updating is performed only for an apparatus needing updating only when needed to prevent the bandwidth of the network from being narrowed. Version information of a file necessary for the operation control for a femto base station apparatus is obtained before performing the operation control. Then, it is confirmed whether or not the obtained version information matches the version information of the file stored in the storage unit. The operation control is performed when matching is confirmed. Contrarily, a version of the file necessary for the operation control is obtained and the file updating is performed when a version confirming unit confirms mismatching of the version information.

Abstract: An IGV opening command is set based on an IGV opening A set by an exhaust gas temperature control section, an IGV opening B set by a compressor surge protective control section, and an IGV opening C set by an exhaust gas pressure protective control section. The value of the IGV opening A, or the value of the IGV opening B, whichever is higher, is selected, the higher selected value, or the value of the IGV opening C, whichever is lower, is selected, and the lower selected value is set as the IGV opening command (gas turbine back pressure rise avoidance priority mode). Alternatively, the value of the IGV opening A, or the value of the IGV opening C, whichever is lower, is selected, the lower selected value, or the value of the IGV opening B, whichever is higher, is selected, and the higher selected value is set as the IGV opening command (compressor surge avoidance priority mode). Alternatively, a switcher switches between these modes.
