Description

The method that relay protection operation is checked
Technical field
The present invention relates to the relay protected operation of Power System Intelligent dispatching of power netwoks technology support system to operate Verification Technology, More particularly to the method that relay protection operation is checked.
Background technology
Relay protection device is the visual plant for ensureing power network safety operation, is the first line of defence of power system. The definite value of relay protection device, pressing plate, which are thrown, moves back the important parameter that state judges as relay protection logic, decides protection act Correctness, also have impact on the performance of protection.With the continuous expansion of power network scale, electric network reconstruction project is continuously increased, electricity The operation of net equipment is more and more frequent, causes power system operating mode often to change., it is necessary to same step when power network mode changes The method of operation of whole relay protection device, including the content such as pressing plate state, operation definite value area code, operation definite value.If operator Member does not adjust the method for operation of relay protection device according to operation rules requirement, then may cause the operation of relay protection device Mode can not meet the requirement of operation of power networks, there is the possibility of false protection or tripping, and then may cause power network weight Major break down.
The content of the invention
Problem to be solved by this invention is to provide a kind of relay protection behaviour checked to relay protection operation result The method for making to check, the method that this relay protection operation is checked solve to cause relay protection to set because scene protection operation is incorrect The standby method of operation can not meet the requirement of operation of power networks, operation of power networks the problem of potential safety hazard is present.
The technical solution adopted in the present invention:The method that relay protection operation is checked, it is characterised in that comprise the following steps:
Relay protection operation rule base is initially set up, using protecting operation rules to define instrument, with the parameter of protection device For regular configuration object, the method for operation of relevant protection device under primary equipment run mode is defined on, the parameter includes pressing plate State, definite value area code, definite value, intake state are moved back in throwing;
Secondly it is real from intelligent grid supporting system technology basic platform acquisition power network to check service processes for protection operation When operation information, obtain the real-time traffic information of relay protection from protection information management main website, and circulate and perform following task:
To each primary equipment object, call primary equipment run mode to differentiate interface, searched from protection operation rule library Rope goes out the protection operation rules of matching, and the method for operation of protection is checked, by operation check result write-in real-time database;Institute Stating primary equipment object includes circuit, bus, main transformer;
Finally protection operation check result picture is shown online, on electric network current diagram or plant stand line chart, passes through equipment The color decision of pel, reflects whether the method for operation of primary equipment relevant protection device meets to protect operation rules will in real time Ask.
Further, described relay protection operation rule base includes protection operation rules table and protection operation sub-rule Table;Protection operation rules table includes rule name, voltage class, device type, primary equipment run mode;Protection operation cuckoo Then table includes relevant device, protection type, protection tricks, measuring point group, measuring point object, state value, rule description;One protection Operation rules object includes a plurality of protection operator rule objects..
Further, described protection operation rules defines instrument definable primary equipment run mode and related protection dress The operation rules put:Firstly the need of rule name, voltage class, device type, primary equipment run mode is set, secondly definition should The sub-rule that operation rules includes, every sub-rule need to set relevant device, protection type, protection tricks, measuring point group, measuring point Object, state value, rule description.A plurality of sub-rule can be increased.
Further, service processes are checked in described protection operation:It is flat from intelligent grid supporting system technology basis Platform obtains power network real-time traffic information, and the real-time traffic information of relay protection is obtained from protection information management main website, and circulation performs Following task:
To each primary equipment object, call primary equipment run mode to differentiate interface, searched from protection operation rule library Rope goes out the protection operation rules of matching, and the method for operation of protection is checked, and primary equipment object includes circuit, bus, master Become;If being unsatisfactory for requiring, operation check result is write in real-time database, related primary equipment is set and checks the mark not passed through Will.
Further, described protection operation check result picture is shown online:In electric network current diagram or plant stand line chart On, by the color decision of equipment pel, reflect whether the method for operation of primary equipment relevant protection device meets to protect in real time Operation rules requirement.
The present invention establishes relay protection operation rule base according to the requirement of regional electric grid relay protection operational procedure.Protection Operation rule library defines the primary equipment run mode related to power system operating mode, and is thrown with the pressing plate of protection device and move back shape The parameters such as state, operation definite value area code, operation definite value, intake state are regular configuration object, are defined on primary equipment run mode The method of operation of lower relevant protection device.
Power network primary equipment model, power network real-time status etc. are obtained from intelligent grid supporting system technology basic platform Data, the method for operation of current electric grid is identified, judge whether the running status of current primary equipment changes, if any change Change, then according to the running status of primary equipment, the protection operation rules of matching searched out from protection operation rule library, using from Protection information management main website (secondary device in-service monitoring and analysis) obtains relaying configuration and protection real-time traffic information, to protection The method of operation checked, judge adjustment after the protection method of operation whether meet associative operation rule requirement, if be discontented with Foot requires, then writes in real-time database operation check result, the mark of " check and do not pass through " is set to related primary equipment, is passed through The color decision of equipment pel, prompting is provided on electric network current diagram or plant stand line chart, while send alarm event prompting behaviour Make personnel.
Beneficial effects of the present invention:Using the method described in the present invention and system, operation rule library is protected by establishing, When power system operating mode changes, whether real-time check relay protection operation result meets the requirement of power system operating mode, prevents Only because parameter setting mistake causes protection that malfunction or tripping occurs, it is ensured that power network safety operation.
