Background technology
For the safe and reliable operation of electrical network, the staff of scheduling O&M class needs each transformer station of periodical inspection, checks and needs to check more frequently when the action frequency of adding up all action frequency, especially equipment that move equipment approaches maintenance number of times.Take Suzhou as example, Suzhou District one total 456Ge transformer station, each station on average has 20 can move equipment, and working strength and the investment in human resources of making an inspection tour work are all very large, and work efficiency is obviously not high.Moreover because there is high-tension electricity in transformer station, tour work belongs to high-risk work post, potential safety hazard is high.Reactive voltage control system data analysis tool can directly record and add up the action frequency of equipment, when the action frequency of equipment approaches maintenance number of times, can send alarm to O&M personnel, prompt facility needs maintenance, can greatly reduce like this O&M personnel and make an inspection tour on-the-spot number of times and working strength, for the intellectuality of operation of power networks contributes.
Summary of the invention
The invention provides the guard method of a kind of reactive voltage control system data analysis tool; it not only can be cost-saving; and do not needing maintainer to go on-the-spot duplicate acknowledgment equipment whether out-of-limit; significantly reduce workload; increase work efficiency, improved the efficiency of reactive voltage control system data analysis and data query.
The present invention has adopted following technical scheme: the guard method of a kind of reactive voltage control system data analysis tool, and it comprises the steps: step 1, determines scope of statistics, desired data kind has: number of equipment action Mr in the time between overhauls(TBO); Ms is counted in initial operation; Reactive voltage control system auto-action number of times Ma; Monitor staff's manual activity number of times Mm; The maintenance number of times upper limit Mmax of certain equipment.Wherein, initial operation is counted Ms and is provided by O&M personnel, and reactive voltage control system auto-action number of times Ma, monitor staff's manual activity number of times Mm are added up automatically by reactive voltage control system; Step 2, calculates number of equipment action Mr in the time between overhauls(TBO): the computing formula of this instrument is Mr=Ms+Ma+Mm, when Mr>=(Mmax-200), and instrument automatic alarm, and out-of-limit all devices is enumerated out; Step 3, data confidentiality measure, the data of this instrument are to be transferred to power supply network III district network from power supply network I district by forward spacer assembly, data can only one-way transmission, guarantees the safety of LiaoⅢ district network, has guaranteed the accuracy of transmission data simultaneously; Step 4, running flow process, after maintenance last time of power supply network equipment, reactive voltage control system is according to method statistic Mr described in step 1 and step 2, when Mr is out-of-limit, notice O&M personnel change equipment needs maintenance, O&M personnel allow maintainer arrive site examining and repairing equipment according to flow process, have overhauled the O&M personnel that report, and notify monitor staff by the Mr zero clearing in reactive voltage control system simultaneously, again statistics, so moves in circles.
In step 4 of the present invention, the out-of-limit situation of Mr is to notify O&M personnel, equipment to need maintenance when number of equipment action only has 200 times apart from stipulated number within the time between overhauls(TBO).
The present invention has following beneficial effect: adopted after above technical scheme, the present invention possesses following functions: 1) basic data query function: study the switch respective model (SF6, vacuum) of each transformer station's reactive apparatus, the date of switch maintenance last time, basic data report query convenient derivation the such as switch allows action frequency, interior auto-action number of times of switch maintenance cycle; 2) data analysis function: research is by month, by the average switching frequency of regional capacitor switch analysis, maximum switching frequency, equipment switching, the equipment accumulative total switching frequency data function that transfinites not.And can inquire about detailed detail; 3) abnormal locking signal statistical function: research reactive apparatus blocks reason, time, number of times inquiry and statistical function; 4) busbar grounding discrimination function: research and analyse 35 kilovolts and the uneven feature of following busbar voltage, judgement busbar grounding also realizes phonic warning prompt facility, so not only reduced human input, save human cost, and reactive voltage control system data analysis can be provided, improve reactive voltage control system data analysis and data query.
