Environmental parameter control system and control method for distribution rooms of several transformer substations in regional power grid

Abstract

The invention discloses an environmental parameter control system and control method for distribution rooms of several transformer substations in a regional power grid. The environmental parameter control system comprises a transformer substation distribution room environmental parameter automatic control background system, wherein the transformer substation distribution room environmental parameter automatic control background system is connected with a transformer substation distribution room environmental parameter automatic control main station system of a regional power grid centralized control center through a private wire network. By adoption of the environmental parameter control system and control method, the following technical problems can be solved: in the prior art, in-stationdistribution room environment regulating equipment is manually controlled, so that heat cannot be dissipated in time, the temperature of switch bodies is increased to a too high level, primary equipment and secondary equipment are subjected to insulation aging, and the safe running of the in-station distribution room environment regulating equipment is seriously influenced; after an accident happens in one distribution room, harmful gas generated from the accident cannot be exhausted and the post-accident treatment is influenced; according to the running mode, the in-station distribution roomenvironment regulating equipment continuously runs for 24 hours and is easily damaged; and an operator on duty is arranged for in-station monitoring in one transformer substation and the demand for unattended transformer substations is not met.

Description

technical field [0001] The invention belongs to the field of automatic control, and in particular relates to an environmental parameter control system and a control method for a power distribution room of a multi-substation in a regional power grid. Background technique [0002] With the continuous acceleration of urban economic development and the increasing demand for electricity, the construction of power grids will continue to accelerate. The substation is the most important link in the four essential links of electric energy generation, transformation, transmission and distribution in the power system, and is the central node supporting the electric energy transmission network. Whether the operation of the substation is normal or not is directly related to the quality of regional power supply. [0003] There are many substation operating equipment installed in important parts such as switch room and capacitor room in the substation. The normal operation of these equipm...

Problems solved by technology

[0009] The technical problem to be solved by the present invention is to provide an environmental parameter control system and control method for the power distribution room of a multi-transformation substation in a regional power grid, so as to solve the problem that the existing heat cannot be manually controlled by the environmental regulation equipment of the power distribution room in the station. If it is released in time, it will cause the body temperature of the switch to rise too high, resulting in the aging of the insulation of the primary and secondary equipment, seriously affecting the safe operation of the equipment; Treatment; the operation mode of the environmental regulation equipment is 24 hours of uninterrupted operation, which is prone to equipment damage; and when the abnormal operation of the environmental regulation equipment will cause the environmental parameters of the substation to change, if it is not found in time, it will lead to the failure of the substation equipment; and There are countless substations in the regional power grid, and the environmental parameters of each substation need to be monitored. The existing technology is to set up on-duty personnel in the substation for in-station monitoring. Each substation needs monitoring personnel, which does not meet the requirements of unattended substations, etc. technical problem
