(2) limit layer
Lifetime cap value is located in limit layer, to be calculated most by rules layer based on data layer data in limit tree
Eventually as a result, the lifetime cap value of mark limit tree, i.e. section are active and the control of backbone point voltage bound requires, no sublayer.
(3) rules layer
With basic data (voltage, electric current, power, topology status including the acquisition of smart grid regulator control system of data Layer
Etc. data) and derivative data (including spinning reserve, load always add, section power always adds etc. non-straight adopt data) based on, according to
Stablize regulation determining rule and requirement, is layered the electronization parsing of implementation rule.Including " regular typing layer " and " logical combination
Two sublayers of layer ", regular typing layer are used for the typing of base level limit, and logical combination layer is for determining base level limit and centre
Logical relation, intergrade limit between grade limit and the logical relation between lifetime cap value.Furthermore it also covers interrelated
" level-one limit ", " intergrade limit ", " base level limit " three parts.
Level-one limit just refers to the lifetime cap value in limit layer, unique limit in all hierarchical structure tops, can
To be that section is active or the control of backbone point voltage bound requires, limit is the lifetime cap of " limit tree ", by intergrade
Limit generates (the usually combination of max, min) by certain logic rules;By " title " (XX grades of limit XX), " customized
Description ", " logical relation with junior limit " three parts are constituted.
Intergrade limit is obtained by base level limit by logical relation, and multilayer (second level limit, three-level limit can be divided
Volume ...), every layer can have multiple sane level limits (e.g., second level limit 1, second level limit 2 ...), can be section it is active or in
The control of centring point voltage bound requires.Upper level in intergrade limit is generated by part next stage limit by certain logic rules
(the usually combination of max, min);By " title " (XX grades of limit XX), " customized description ", " logic with junior limit
Relationship " three parts are constituted.
Base level limit is generated by " grid operation mode ", " power grid control condition " according to standardized rule, can be
Section is active or the control of backbone point voltage bound requires.Each base level limit generates unique value.By (XX grades of " title "
Limit XX), " customized description ", " regular group " three parts constitute.
Without direct rule typing, only base level limit carries out regular typing, main for level-one limit, intergrade limit
Effect be characterize with basic limit be divide each group rule between logical relation.
2, regular typing is carried out, is specifically changed according to digital & analog signal value, equipment working condition and the electric network model of grid equipment
Situation is carried out the Auto-matching of the method for operation and lifetime cap value using limit tree-model, determines the operation of current electric grid section
Mode and lifetime cap value;The rule for fitting through typing of the method for operation and the comparison realization of collected electric network state, really
Lifetime cap value is further determined that after determining the method for operation.Such as: if rule be " when brocade Soviet Union dc power be more than 100MW, finally
Stability limitation is 200MW;When brocade Soviet Union dc power is 50-100MW, final stability limitation is 150MW ", here brocade Su Zhiliu function
Rate is more than that 100MW is a kind of section method of operation, and it is another section method of operation that brocade Soviet Union dc power, which is 50-100MW, according to
The dc power measurement of brocade Soviet Union can further determine that final stability limitation.
Network stability control regulation electronization analytic modell analytical model should first carry out layering definition in use, rear to carry out specifically
Regular typing.Logical relation between limits at different levels by the way of clicking " title " and " canonical function " (max, min) into
Row typing.
Base level limit rule typing:
Base level limit rule is that foundation divides group into base level limit.Every group of rule uniformly imposes a condition number, value
Logic (max or min that take each rule).The standard reference pattern of single rule is as follows:
Mode | Condition 1 | Condition 2 | …… | Limit |
(1) mode: from selection in " mode collection ";It as a result is "Yes" or "No".
(2) condition: from voltage, the electric current, power, topology for choosing the acquisition of smart grid regulator control system in " basic underlying variables collection "
The basic underlying variables such as state, Selecting operation accords with from standard logic operation library, carries out condition typing.It as a result is preferably "Yes" or "No".
(3) limit: directly filling in, or voltage, electricity that smart grid regulator control system acquires are chosen from " basic underlying variables collection "
The basic underlying variables such as stream, power, topology status, Selecting operation accords with from standard logic operation library, carries out condition typing.As a result it is preferably
Numerical value.
Basic underlying variables alternative solution
When the basic underlying variables such as voltage, electric current, power, the topology status of the acquisition of smart grid regulator control system are unable to characterize stabilization
The condition member or mode member of limit, need to substitute basic underlying variables.Basic underlying variables substitution is only in a certain base level limit
Effectively (regular group divided by base level limit).
Generated after basic underlying variables substitution N kind (as long as meeting any substitutional relation is a kind of alternative case, N can be 0, this
Shi Wuxiao) equivalent basic underlying variables situation in basic underlying variables " substitution " this base level limit rule group in each case, obtains only
One section is active or the control of backbone point voltage bound requires namely limit.
The unified value logic for setting each alternative case (the case where containing not substituted) of basic underlying variables substitution (respectively substitutes feelings
Unique limit value under condition takes max or min).
The standard scheme of single substitutional relation:
1) substitution meets condition: from voltage, the electric current, function for choosing the acquisition of smart grid regulator control system in " basic underlying variables collection "
The basic underlying variables such as rate, topology status, Selecting operation accords with from standard logic operation library, carries out condition typing.As a result it should be "Yes"
Or "No".
2) object: the original variable quantity of substitutional relation is substituted, from selection smart grid regulator control system in " basic underlying variables collection "
The basic underlying variables such as voltage, electric current, power, the topology status of acquisition, Selecting operation accords with from standard logic operation library, carries out condition
Typing.Pay attention to as a result should be numerical value herein for the expression for being changed original variable.
3) object: the object variation amount of substitutional relation is substituted, from selection smart grid regulator control system in " basic underlying variables collection "
The basic underlying variables such as voltage, electric current, power, the topology status of acquisition, Selecting operation accords with from standard logic operation library, carries out condition
Typing.Pay attention to as a result should be numerical value herein for the expression for being changed original variable.
Main mode and condition positioning
Maximum, min is looked for look for minimum (being then mulitpath when value is identical) according to max, backtracking navigates to specific base level
Limit, i.e. section are active or the control of backbone point voltage bound requires.
By same rule, concrete mode and condition, as main mode and condition are navigated to.
Because being likely to occur mulitpath, final result may be several leading base level limits, main mode and condition.
Variable pond, mode pond and regular pond
The basic underlying variables such as voltage, electric current, power, the topology status of the acquisition of smart grid regulator control system in all limit trees
It gathers to form in " variable pond ", the method for operation definition set in all limit trees forms " mode pond " together, owns
Base level limit regular collection in limit tree forms " regular pond " together.All variables, mode and rule in " pond " are equal
It can be called for different independence " limit tree ", to improve parsing programming efficiency;Not by all in certain " limit tree " calling " pond "
Variable, mode and rule have no effect to " the limit tree ".
3, the content in limit tree is shown on a display screen to monitor, and passes through the specific of change " basal profile variables set "
Data source, may be implemented this method in D5000 system real time execution monitoring with comprehensive intelligent alarm, a few days ago plan arrange with
Check, safety on line analysis, the fusion in a few days planned in the modules such as check, the monitoring of Real-time Balancing ability, in a few days spot exchange are answered
With, for application provide unified model, data, CASE, network communication, man-machine interface, system administration etc. service.Real-time state operation
The Auto-matching of mode and stability limitation is mainly the limit under the method for operation and section and different running method using definition
Value is completed in real time according to the digital & analog signal value of grid equipment, equipment working condition and the specific situation of change of electric network model to current
Grid operation mode and related limit parsing.When grid operation mode changes, the collected voltage of grid equipment, electricity
Stream, power, topology status change, for example, being a kind of operation of power networks side when certain interconnection load factor is 50%
Formula;It is another grid operation mode when this interconnection load factor is 80%.By acquiring the negative of this interconnection
Load rate data, so that it may perceive the variation of the method for operation.Grid operation mode can be quickly generated new section, update after changing
Limit value, discovery more generate alarm in limited time.The future-state method of operation and stability limitation Auto-matching according to Plant maintenance plan or
Forecast accident is carried out tidal current analysis based on power grid typical way and calculates the method for operation for determining section in following a period of time
And limit value.
