The present invention will be further described in detail below in conjunction with the accompanying drawings.
As shown in figure 3, the invention provides a kind of pole control system of layer-specific access system, including pole control system, standby without
Power control main website A and B, and for gathering the measure and control device of each layer-specific access AC network median filter group information.Wherein pole 1
The pole control system A and pole control system A of pole 2 constitutes main pole control system, the pole control system B of the pole 1 and pole control system B of pole 2 composition redundancy electrode controls
System；Standby is idle, and control main website A is communicated to connect with the measure and control device of main pole control system and each AC network respectively, and standby is idle
Control main website B is communicated to connect with the measure and control device of redundancy pole control system and each AC network respectively；Standby is idle, and control main website A leads to
The running status of each AC network wave filter/capacitor of each AC network measure and control device Real-time Collection is crossed, and is uploaded to master
Pole control system；Standby is idle, and control main website B passes through each AC network wave filter/electric capacity of each AC network measure and control device Real-time Collection
The running status of device, and it is uploaded to redundancy electrode control system；
Standby is idle to be communicated between control main website and measure and control device by lan network, for gathering each layer-specific access exchange
Network median filter group information；
According to Profibus communication protocol communications between pole control system and the idle control main website of standby, standby is idle, and control is led
Each layer-specific access AC network median filter group information that will be gathered of standing is uploaded；
By LAN Network Communications between pole control system, for relevant information of the interaction on the idle control of standby.
Standby is idle, and control function is mainly integrated in pole control system, is partly arranged in the idle control main website of standby.Pole
The absolute minimum filters table of Main Basiss in control system, completes active power regulation；Standby is idle, and control main website Main Basiss are big
Group busbar voltage, completes wave filter/capacitor excision.
Implement process as follows：
Two AC network median filter/capacitor running statuses that pole control system is uploaded according to the idle control main website of standby
Information (wave filter/capacitor input state, wave filter/capacitor exit state), and it is (complete to combine current system operating condition
Pressure/brownout operation, power/current control model, bipolar layer control normal/failure etc.), carry out power definite value meter under current working
Calculate.When the idle control function of standby is effective, pole control system is according to current each AC network median filter/capacitor input

Energy.
Below by taking certain layer-specific access ± 800KV extra-high voltage direct-current transmission engineerings as an example, inventive concept is carried out further
Explanation.
As shown in figure 4, be the structural representation of layer-specific access extra-high voltage DC transmission system, including 500KV and 1000KV
Two AC networks.
500KV AC networks configure 14 groups exchange (three big groups) alternating current filter, respectively 8 groups HP12/24 (A), 1
Group HP3 (C) and 5 groups of SC (D)；
1000KV AC networks configure 10 groups exchange (two big groups) alternating current filter, respectively 6 groups HP12/24 (A)
And 4 groups of SC (D)；
Wherein HP12/24 is 12/24 double tunning high-pass type alternating current filter, and HP3 is 3 single tuning high-pass type filtering
Device, SC is shnt capacitor.
The each group of observing and controlling of alternating current filter of correspondence is all separate configurations, one measure and control device of correspondence per a small group, respectively
The different mailing address of configuration, it is idle with standby respectively to control master station to communicate.Access infrastructure is as shown in Figure 3.
Situation is exited when the control main frame (integrated idle control function) of the redundancy in bipolar layer control system is abnormal
Under, start the idle control function of standby configured in pole control system, by ac filter in Real-time Collection each AC network
Device/capacitor running status, according to the absolute minimum filters power table of comparisons, realizes under current operating condition, system transfers
The control of power
It is as follows that logic is cut in control master station overvoltage that standby is idle soon：
As 1.1p.u ＞ Uac ＞ 1.05p.u., 1 group's alternating current filter is cut off every 1s, until under minimum power
Absolute minimum filters.
When Uac ＞ 1.1p.u. cut off 1 group's alternating current filter every 300ms, until the absolute minimum filter under minimum power
Ripple device.
Standby is idle control station is according to ac bus voltage condition and its embedded wave filter switching sequence list, surgical filtering
Device/capacitor.
Wherein, 500KV AC networks alternating current filter/capacitor switching is sequentially：
1000KV AC networks alternating current filter/capacitor switching is sequentially：
Standby is idle, and control main website corresponds respective measure and control device according to above-mentioned excision order, and limit is surmounted in voltage
When, sequentially surgical filtering device/capacitor, for same type wave filter/capacitor, first cut principle execution according to first throwing.
