Embodiment Construction

[0020] There are generally two types of screen cabinets in the screen cabinet system:

[0021] 1) The screen cabinet containing the control or protection host, there may also be related I / O interface devices in the cabinet, called the host screen, in which the control or protection host is the core processing unit of the DC system. The O interface device obtains status and measurement information, and sends control commands through the field bus;

[0022] 2) The screen cabinet with only measurement and control I / O or communication I / O interface is called an interface screen. This type of screen cabinet is only responsible for collecting status and measurement information, which is sent to the control and protection host through the field bus, that is, the host screen. At the same time Receive and execute commands to control and protect hosts.

[0023] Such as figure 1 The schematic diagram of equipment failure indication in the DC control protection panel shown in the tradit...

Abstract

A method for indicating equipment faults in a screen cabinet. The screen cabinet includes a screen cabinet containing a control or protection host and a screen cabinet containing only a measurement and control I / O interface or a communication I / O interface, which are respectively called a host screen and an interface screen. Equipment indicator light and screen cabinet indicator light, the equipment indicator light corresponds to the equipment in each screen cabinet, and the screen cabinet indicator light is used to indicate the operating status of the equipment in the screen cabinet and other equipment working with it. According to the characteristics of DC control and protection, the present invention performs perfect self-monitoring on all equipment in the control and protection system, prompts through the indicator light outside the screen cabinet, and judges whether all equipment in a certain cabinet is in a good operating state , when any equipment component in the cabinet is abnormal, it will be prompted by the indicator light of the screen cabinet; at the same time, it can also reflect the status of the screen cabinet directly related to it, and finally can accurately and intuitively reflect the true meaning of the screen cabinet and its system on the working status.

Description

technical field [0001] The invention relates to a screen cabinet status display of a DC transmission control protection system, and is especially suitable for the realization of the monitoring logic of the DC control protection system in a DC converter station and the status indication of the screen cabinet, and is a method for indicating equipment faults in the screen cabinet. Background technique [0002] HVDC transmission has been widely used due to its unique advantages, such as long distance, high power, asynchronous networking, fast power adjustment, power flow controllability, and transmission economy. [0003] The control and protection system of DC transmission is the center of the DC transmission system. It controls the entire process of AC and DC power conversion and DC power transmission, and protects all electrical equipment in the converter station and DC transmission lines from damage caused by electrical faults. [0004] A control and protection system in a g...
