Detailed Description
In order to make the objects, features and advantages of the present invention more obvious and understandable, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The embodiment of the application provides a method, a system and equipment for monitoring and protecting the pressure of a capacitor in a converter valve, which are used for solving the technical problem that the operation safety of the flexible direct current converter valve is influenced by the fact that no protective measures are taken for the safety accident of the capacitor in the flexible direct current converter valve due to overlarge pressure in the prior art.
Fig. 1 is a flowchart illustrating steps of a method for monitoring and protecting a pressure of a capacitor in a converter valve according to an embodiment of the present disclosure, and fig. 2 is a schematic structural diagram illustrating a capacitor of the method for monitoring and protecting a pressure of a capacitor in a converter valve according to an embodiment of the present disclosure.
As shown in fig. 1, an embodiment of the present application provides a capacitor pressure monitoring and protection system in a converter valve, which is applied to a flexible dc converter valve, where the flexible dc converter valve includes a capacitor and a power module, and a pressure switch element 102 and a pressure release element 103 are disposed on the capacitor 101.
It should be noted that the pressure switch element is mainly used for executing an action according to the pressure on the capacitor and sending an action signal; the pressure release element is mainly used for releasing the pressure in the capacitor. The pressure switch element may be a pressure switch and the pressure release element may be a pressure valve. The capacitor is a direct current capacitor. In this embodiment, pressure switch and pressure valve are installed simultaneously to the condenser, and pressure switch and pressure valve mutually support, correspond two kinds of different fault status, and the pressure valve corresponds comparatively fast, unbalanced pressure rise, and pressure switch corresponds comparatively slow pressure rise.
The method for monitoring and protecting the pressure of the capacitor in the converter valve comprises the following steps:
s1, acquiring action signal data of a pressure switch element in a capacitor in real time.
It should be noted that when a short-circuit fault occurs inside a capacitor of a certain power module of the flexible dc converter valve, the internal pressure of the capacitor may be increased, and in step S1, it is mainly obtained in real time whether the flexible dc converter valve dc capacitor sends an operation signal. The action signal of the capacitor refers to whether a pressure switch element in the capacitor is triggered by the internal pressure of the capacitor so as to determine whether to send out the action signal.
And S2, obtaining the state information of the pressure switch element through the action signal data.
The operation threshold of the pressure switching element is preferably 30 kPa. In step S2, the state information of the pressure switch element is obtained mainly from the operation signal data acquired in real time. In this embodiment, if the internal pressure of the capacitor is greater than the operation threshold of the pressure switch element, and the obtained operation signal data indicates that the pressure switch element sends out an operation signal, the state information of the pressure switch element indicates that the pressure switch element operates; and if the internal pressure of the capacitor is not greater than the action threshold value of the pressure switch element, obtaining action signal data that the pressure switch element does not send out an action signal, and determining that the pressure switch element does not act according to the state information of the pressure switch element.
S3, if the state information is the action state of the pressure switch, controlling a bypass switch of the power module to be closed; and then if the internal pressure of the capacitor continuously rises to the release threshold value of the pressure release element, the pressure release element works to release the pressure of the capacitor.
It should be noted that the release threshold of the pressure release member is preferably 50 kPa. In this embodiment, only the state of the pressure switch element is the operating state of the pressure switch, and at this time, the bypass switch of the power module corresponding to the capacitor is controlled to be closed, so that the power module where the faulty capacitor is located is cut off from the loop, and the protection effect on the flexible-direct converter valve is achieved. Meanwhile, the pressure release element of the capacitor works to release the pressure inside the capacitor, so that the capacitor is prevented from generating worse faults.
In this application embodiment, through the cooperation of pressure value between pressure switch and the pressure valve, correspond two kinds of different fault status, the pressure valve corresponds comparatively fast, unbalanced pressure rise, and pressure switch corresponds comparatively slow pressure rise. Wherein the pressure switch acts in preference to the pressure valve to ensure the safety of the capacitor. To ensure reliable operation of the pressure switch, the operating value of the pressure switch (i.e., the operating threshold of the pressure switch element) may be lower than the operating value of the pressure valve (i.e., the release threshold of the pressure release element). When the action value of the pressure switch is selected to be 30kPa, and when the pressure difference between the inside and the outside of the capacitor reaches more than 30kPa, the pressure switch acts to control the bypass switch of the power module to be closed. When the action value of the pressure valve is selected to be 50kPa and the pressure difference between the inside and the outside of the capacitor reaches more than 50kPa, the release voltage action of the pressure valve releases the internal pressure of the capacitor, thereby playing a role in protecting the capacitor. 30kPa is the minimum motion value selectable for the pressure switch. The release threshold of the pressure release element and the actuation threshold of the pressure switch element may be set as desired, and the values selected in this embodiment are not unique.
The application provides a capacitor pressure monitoring and protecting method in a converter valve, which comprises the following steps: acquiring action signal data of a pressure switch element in a capacitor in real time; obtaining the state information of the pressure switch element through the action signal data; if the state information is the action state of the pressure switch, controlling a bypass switch of the power module to be closed; and then if the internal pressure of the capacitor continuously rises to the release threshold value of the pressure release element, the pressure release element works to release the pressure of the capacitor. When a capacitor of the flexible direct current converter valve fails, the method for monitoring and protecting the pressure of the capacitor in the converter valve obtains action signal data of a pressure switch element in the capacitor in real time, if the internal pressure of the capacitor is larger than an action threshold value of the pressure switch element, the pressure switch element executes action, only an action signal is sent out when the pressure switch element executes the action, and a bypass switch of a power module is controlled to be closed according to the action signal, so that the power module where the failed capacitor is located is cut off from a loop, and the protection effect on the flexible direct current converter valve is achieved; after a bypass switch of the power module is closed, if the internal pressure of the capacitor continuously rises to a release threshold value of the pressure release element, the pressure release element of the capacitor works to release the internal pressure of the capacitor, so that the capacitor is prevented from generating worse faults.
