Embodiment Construction
[0019] see figure 1 , is a flow chart of an optimization method for the operation of a converter station monitoring system provided by this application. like figure 1 As shown, the method includes the following steps:
[0020] Step 101, receiving a first monitoring signal.
[0021] The first monitoring signal is a signal of the monitoring converter station of the monitoring system. A converter station refers to a station established in a high-voltage direct current transmission system to complete the conversion of alternating current to direct current or direct current to alternating current, and to meet the requirements of the power system for safety, stability and power quality. During the monitoring process of the converter station by the monitoring system, various signals need to be monitored, such as protection action signals, telemetry signals, electrical remote signaling signals, circuit breaker remote control signals, circuit breaker external switch remote control s...

The invention discloses a method and a device for optimizing operation of a converter station monitoring system, and relates to the technical field of electric power systems. The method and the device are invented for solving a problem that an existing converter station monitoring system is low in operation efficiency. The method mainly comprises: receiving a first monitoring signal; searching a first priority of the first monitoring signal; configuring a first monitoring period of the monitoring system as a data acquisition period corresponding to the first priority; according to a first control period, receiving a second monitoring signal, and meanwhile recording operation time of the first monitoring period; if a second priority of the second monitoring signal is higher than the first priority, configuring a second monitoring period of the monitoring system as a data acquisition period corresponding to the second priority; if the operation time is longer than preset threshold time, configuring the second monitoring period of the monitoring system as a data acquisition period corresponding to a secondary adjacent priority of the first priority. The method and the device are mainly applied in a process of monitoring a converter station.
Description
technical field [0001] The present application relates to the technical field of power systems, in particular to a method and device for optimizing the operation of a converter station monitoring system. Background technique [0002] With the rapid development of HVDC transmission technology, the converter station has gradually become an important part of the power system. Its function is to realize the AC-DC conversion of the DC transmission system and control the operation of the DC transmission system. It is the core of the DC transmission project. part. Compared with the traditional substation, the converter station mainly has the following characteristics: the equipment composition is complex, and at the same voltage level, in addition to the equipment in the substation, there are also converter valves, filter fields, DC fields, valve cooling systems, air conditioning systems, DC Control and protection systems, etc.; the number of equipment is huge, and the number of p...
