25、 station essential auxiliary load load whose failure will affect the conversion capability of the HVDC converter station (e.g. valve cooling), as well as load that must remain working in case of complete loss of a.c. power supply (e.g. battery chargers, operating mechanisms) NOTE Total “operating lo
26、sses” minus “no load operation losses” may be considered as being quantitatively equivalent to “load losses” as in conventional a.c. substation practice. 3.2 Letter symbols Replace the definitions of letter symbols , , Id, R and U v0as follows: (trigger) delay angle, in radians (rad) overlap angle,
27、in radians (rad) I ddirect current, in amperes (A) R resistance value, in ohms ( W) U v0r.m.s. value of the phase-to-phase no-load voltage on the valve side of the converter transformer excluding harmonics, in volts (V) 4.2.1 Outdoor standard reference temperature Add, after the first sentence, the
28、following new sentence: Corresponding valve hall temperature may be defined by the supplier if necessary. Add the following note: NOTE If not defined, the wet-bulb temperature is recommended to be 14 C which corresponds to approximately 50 % RH at 20 C dry bulb temperature. 4.3 Operating parameters
29、Add the following words at the end of the fourth paragraph: “ or as decided by the control system for the defined operating condition”. 4 61803 Amend.1 IEC:2010 5.1 Thyristor valve losses Replace, in the first line of the third paragraph, the words “Symbol t combines ” with “Symbol th combines ”. 5.
