Problems solved by technology
Since a substation generally has multiple outdoor boxes, such as terminal cabinets, mechanism cabinets, etc., and the distance from the control room varies from a few meters to several hundred meters, using method 1 cannot monitor the information of each outdoor box in real time, and requires the inspector to frequently patrol inspection, occupying human resources, and because of its inconvenient use and control, it is also easy to cause safety hazards
Most substations now use the second method to achieve anti-condensation control. Although this method can solve the problem of not being able to obtain the temperature and humidity information of each cabinet in the station in time, it requires each cabinet to be connected to a set of control fan cables and sensor cables. The volume is huge, the cost of cables is high, and due to the large power consumption of the fan, the power requirements for the control room are also very high, which causes serious waste of resources and is not conducive to the commissioning and maintenance of the substation control system

The embodiment of the invention discloses a condensation prevention control method and a system for an integrated converting station, which are used for accurately detecting the condensation state of an outdoor cabinet of the converting station in real time to realize integrated intelligent control over condensation prevention of the converting station. The method comprises the following steps of: connecting a field bus with the outdoor cabinet to constitute a monitoring object; setting communication parameters and control parameters by using a control input module, and transmitting the parameters to an industrial control mainboard; periodically acquiring humiture information of the monitoring object by using a humiture sensor to form humiture data; summarizing and processing the humiture data by adopting the industrial control mainboard to form summarized data, and controlling the action of the controller; and controlling the in-service and out-of-service of a logic control dehumidifier by using the controller to further control the humiture of the outdoor cabinet and achieve the technical effect of preventing condensation.
Description
technical field [0001] The invention relates to the field of integrated control, in particular to an integrated control method and system suitable for substation anti-condensation. Background technique [0002] Condensation is very common in daily life, especially in places with large temperature difference between day and night or humid air. There may be condensation on the top and inside of the outdoor cabinet of the substation. The condensation problem in the substation box will lead to problems such as insulation degradation, corrosion, and short circuit of internal devices, which greatly threatens the safety of the power grid. In order to ensure the insulation performance of the internal device of the outdoor cabinet of the substation and ensure the reliable operation of the device, it is necessary to take corresponding anti-condensation measures. [0003] There are two main methods of anti-condensation control in existing substations. The first method is to install a...
