Abstract

A control system for controlling parallel connected power converters includes a data processing system (101-103) configured to form, for each power converter, a frequency droop value (Δfdroop_n) based on electric power of the power converter, and to change a frequency reference (fref_n) of each power converter by the frequency droop value of the power converter. The data processing system forms an arithmetic average of the frequency droop values, forms a correction value based on the arithmetic average of the frequency droop values, and changes the frequency reference (fref_n) of each power converter by the correction value to drive the arithmetic average towards zero. The driving the arithmetic average towards zero reduces undesired frequency drift of the power converters.

Abstract

A method for operating a vapour compression system (1) is disclosed. A cut-in temperature, a high temperature alarm limit and a high temperature alarm delay time are set. A maximum acceptable relative decay value is derived, based on the high temperature alarm limit and the high temperature alarm delay time. The vapour compression system (1) is operated while monitoring a temperature inside a refrigerated volume and continuously deriving a weighted mean temperature prevailing inside the refrigerated volume, during a moving time window of a predefined length. In the case that the weighted mean temperature inside the refrigerated volume exceeds the cut-in temperature, a timer is started, and a delay time is derived, based on the weighted mean temperature and the maximum acceptable relative decay value. A warning is generated when the timer reaches the derived delay time.

Abstract

A dual-active-bridge converter comprises a first H-bridge (101) for producing first voltage pulses which are alternately positive and negative, a second H-bridge (102) for producing second voltage pulses which are alternately positive and negative, and a transformer (103) comprising a first winding (104) receiving the first voltage pulses and a second winding (105) receiving the second voltage pulses A controller (106) of the converter changes temporal widths (T1, T2) of the first and second voltage pulses and a phase-shift between the first and second voltage pulses when there is a need to change a distribution of power losses between a core structure of the transformer and power electronic switches of the H-bridges. Thus, the power loss distribution can be optimized in different operational modes, and the power loss distribution can be changed in situations where a part of the converter is at a risk of overheating.

Abstract

A cooling system (10) includes a compressor (12) arranged for feeding compressed refrigerant to a condenser (18) and at least one inlet valve (36) with variable opening degree (OD) for feeding at least partly condensed refrigerant to an evaporator (34). Th evaporator (34) comprises a plurality of evaporator outlet pipes (46) connected to a common return pipe (44) arranged for feeding refrigerant back to the compressor (12). At least one temperature sensor (S1) is arranged on one of the evaporator outlet pipes (46a) for sensing an outlet pipe temperature Tout. In a calibrating phase the cooling system (10) is operated with varying opening degree (OD) of the inlet valve (36). The outlet pipe temperature Tout is monitored. A rapid change of the outlet pipe temperature Tout in response to the varying opening degree (OD) is identified and a control set point value (OHset) is determined based on the outlet pipe temperature Tout. In an operating phase the cooling system (10) is operated by controlling, based on a reading of the temperature sensor (S1), the opening degree (OD) of the inlet valve (36) to achieve the control set point (OHset).
