A system for cooling a solar power plant is provided. The system has a foundation, a protective housing built on the foundation, and one or more heat sources inside the protective housing. An air inlet can provide a cooling air flow from outside the protective housing to inside the protective housing, and an air outlet can allow an air flow heated by the at least portion of the heat sources to exit the protective housing. An air duct system within the foundation can direct at least part of an incoming air flow to another part in the protective housing.

Solar power plant

A method of optimizing one or more starting parameters of a solar power generator system and a solar power generator system, wherein the solar power generator system includes a solar panel array and a converter for converting power obtained from the panel array. The method can include measuring an output voltage of the panel array, comparing the output voltage with a starting voltage (V), starting the solar power generator system when the output voltage of the panel array exceeds the starting voltage (V), measuring the obtained power from the solar panel array after a morning start, comparing the obtained power with a known limit value, and changing the one or more starting parameters on the basis of the comparison of power.

Starting of a solar power plant

The invention relates to a veneer lathe knife assembly comprising supported by a frame assembly a knife mounting beam ( ) and a nose bar beam ( ), both of which having a front portion ( ) for holding a cutting knife ( ) and a nose bar ( ), respectively, and a stiffening rear portion. The knife mounting beam ( ) and the nose bar beam ( ) are adapted movable relative to each other on the frame assembly so as to permit adjustment of the knife gap formed between the cutting knife ( ) and the nose bar ( ). Heat transfer means ( ) are adapted to the stiffening rear portion of both the knife mounting beam ( ) and the nose bar beam ( ). Both the knife mounting beam ( ) and the nose bar beam ( ) have placed thereon, in a close vicinity to the knife ( ) and the nose bar ( ), at least one first set of temperature sensors ( ) disposed in predetermined positions along the length of the knife and the nose bar. Furthermore, both the knife mounting beam ( ) and the nose bar beam ( ) have placed thereon, at a distance from the knife ( ) and the nose bar ( ), at least one second set of temperature sensors ( ) disposed in predetermined positions along the length of the knife and the nose bar, whereby the heat transfer means ( ) placed in the stiffening rear portion ( ) of both the knife mounting beam ( ) and the nose bar beam ( ) are adapted controllable for adjusting the respective portions of the knife mounting beam and the nose bar beam under feedback from the second set of temperature sensors to a temperature value derived from the measurement signal given by the first set of temperature sensors.
