Embodiment Construction

[0055] In order to make the objectives, technical solutions, and advantages of the present invention clearer, the various embodiments to be described below will refer to the corresponding drawings. These drawings constitute a part of the embodiments, which describe various possible implementations of the present invention. Kind of examples. It should be understood that other embodiments may be used, or structural and functional modifications may be made to the embodiments listed herein, without departing from the scope and essence of the present invention.

[0056] In the sequence control method, the actions of each device can be set with strict interlocking control conditions. Whether it is automatic sequence control or manual control of a single device, as long as the action conditions of the device are not met, the device will be locked, thereby further reducing The misoperation rate of operators is improved. In addition, the sequence control method also includes a manual / aut...

Abstract

The invention discloses a control method for a ventilation system of a nuclear power station. The control method comprises an inspection step of inspecting states of the ventilation system and ventilation equipment, a running step of performing a ventilation system starting sequence control process when the ventilation system meets the running conditions, a start alarm step of giving an alarm in 90 seconds when ventilation system sequence starting is of failure and returning to the inspection step, and a reset step of resetting a signal of the ventilation system and inspecting the state of the ventilation equipment. According to the control method, by adopting the sequence control technology for the ventilation system, the operation steps of running staffs are simplified, the error action probability of the running staffs is reduced, the automation level of the system is greatly increased, and the system efficiency is improved.

Description

Technical field [0001] The invention relates to the technical field of nuclear power, in particular to a control method of a ventilation system of a nuclear power plant factory building. Background technique [0002] With the development of microelectronics, power electronics, computers and automatic control theory, the degree of modern industrial automation is getting higher and higher. As a part of industrial automation, sequential control technology has been widely used in industry. [0003] Sequential control method is a control technique in which control actions are carried out successively in accordance with a preset sequence or a certain logically set sequence. Using the sequential control method, the embodiment of the present invention sets the control logic of the equipment in advance according to the equipment startup and shutdown requirements of the air supply and exhaust system in the ventilation system, and the operator only needs a button to make the equipment in the ...
