Description
Technical field
The present invention relates to the power transformation technology in power system, especially a kind of convergence control cabinet realizes load based on single humiture sensor and throws the method cut.
Background technology
Traditional technical scheme adopts one group of humiture sensor substantially, or 2 groups of humidity sensors, and only a few is 3 groups of humiture sensors; Being divided into heating type, cooling type or dehumidification type with its matched load, load group number is 1 group, 2 groups or 3 groups. Layouting of humiture sensor is comparatively random, the not Switching Strategy of clear and definite sensor distributing and coupling. The volume of the outdoor convergence control cabinet of substation is general relatively big, takies space bigger. The load adopted be substantially all heating load (high or low power differs, quantity also difference), is configured with band filter screen ventilation opening on a small quantity or vent window is opened at cabinet top; Humiture sensor configuration quantity differs, and uneven class size installs position random; Arrange throwing to cut load control valve value and substantially lean on experience, it does not have unified setting; Substantially can not solving solidifying dew potential problem, current consumption is relatively big, and particularly when summer high-temperature, the temperature in cabinet is too high. The control strategy cutting load thrown by single humiture sensor is the low wet mode of high temperature substantially, and strategy criterion is single, can not better solve condensation problem.
Traditional sensor distributing mainly contains two kinds, and typical humiture sensor throwing as shown in Figure 1 is cut the throwing of the intelligent humiture sensor shown in load electrical schematic diagram and Fig. 2 and cut load electrical schematic diagram.
In Fig. 1, typical case's humiture sensor is thrown and is cut load arrangements 1 to humiture sensor, by the humiture situation detected in outdoor convergence control cabinet, system is according to set Switching Strategy, throw respectively and cut three class loads, namely heat up load, cooling load and humidity load, thus builds the humiture meeting target.
In Fig. 2, intelligent humiture sensor is thrown and is cut load arrangements three tunnel humiture sensor and three tunnel loads, and the Switching Strategy of the program is as follows:
(1) computer heating control: start: temperature��design temperature (lower limit); Humidity >=setting humidity
Stop: temperature >=design temperature (lower limit)+temperature return difference; Humidity��setting humidity-humidity return difference
Fan control: start: temperature >=design temperature (upper limit);
Stop: temperature��design temperature (upper limit)-temperature return difference.
Scheme one is provided with one pair of humiture sensor, when outdoor cabinet is bigger, humiture distribution in cabinet is uneven, when employing one is to humiture sensor, the variation range gathering temperature-humidity signal can be restricted, so load is thrown and cut and also can be affected, then can have influence on follow-up differentiation with throwing is cut, be related to and solidifying reveal odds.
In scheme two, 3 tunnel load loads comprise 3 road heating loads and 3 tunnel fan load, and condition of loading is comparatively complicated, and it is comparatively complicated that load strategy is cut in configuration load and throwing. The valve value layouted and arrange that priority is directly limited to the humiture sensor mated is started between load and load, affect its susceptibility, and the throwing of load when cutting length be directly connected to electric energy consumption electricity, and then have influence on the prevention that humiture in cabinet is uniformly distributed and coagulates dew hidden danger.
