Abstract
The invention discloses a total life cycle management method for relay protection products, which comprises the following steps of: analyzing and evaluating the producing, processing, debugging, storing, transporting, running and maintaining processes of the relay protection products; setting different weights according to the time point and the running state of each process; classifying the relay protection products according to the type of the relay protection products; and calculating an expected set value of each relay protection product in a station level and a system level by synthesizing the information of the above steps, and establishing a relay protection product station-level management database and a relay protection product system-level management database. In the method, the producing, processing, debugging and maintaining processes, and the like of the products are watched and analyzed, and the total life cycle of the relay protection products is managed; moreover, the running state of the products is evaluated so as to ensure that the products can run reliably.
Description
Technical field
The present invention relates to a kind of method that the relay protection of power system product life cycle is managed, belong to the electrical equipment technical field.
Background technology
Relay protection is the important secondary device of electric system, must be reliably, rapidly, selectively fault element is excised from electric system, and make fault element avoid continuing to be destroyed, guarantee that other non-fault parts recover normal operation rapidly.The develop rapidly of the widespread usage of high-performance processor and large scale integrated circuit technology has greatly promoted the development of digital protective relay technology.Because the equipment of serving engineering site receives the influence of electromagnetic interference (EMI), high temperature wet environment easily; The hardware performance of the digital protective relay product of high volume applications exists the product life cycle rule, therefore must carry out the hardware longevity management to the relay protection product.
Hardware is intact to be an essential condition that guarantees the good operation of relay protection device.Hardware longevity management at present is a weak link, guarantee that the relay protection safe and reliable operation just must be to protecting the device hardware life-span manage.This managerial demand extends to the final user from manufacturer, and it is retired to extend to product from production.
Summary of the invention
The objective of the invention is the relay protection products-hardware is carried out lifecycle management, guarantee the product reliability service, can assess, analyze the product operation conditions simultaneously, for product provides the planning foundation in process links such as production, processing, debugging, maintenances.
In order to realize above-mentioned functions, the present invention provides following technical scheme:
The present technique scheme is to pay close attention to each main time point, and the relay protection products-hardware is carried out lifecycle management.
A kind of full life cycle management method that is used for the relay protection product is characterized in that, comprises following steps:
Step 1: relay protection production, processing, debugging, stock, transportation, operation, maintenance process are carried out analysis and evaluation;
Step 2: time point and operation conditions according to each process are provided with different weights;
Step 3: the type according to the relay protection product is classified it;
Step 4: the information of comprehensive above-mentioned steps, the life cycle calculations value of computer installation level, system-level interior each relay protection product is set up relay protection product station level, system-level management database.
The life cycle calculations value is calculated by following arithmetic expression:
A
kThe expression weight is used for indicating various process to the products-hardware effect on service life, is provided with according to being operating experience, can adjust according to actual conditions;
T
kRepresenting operation time, is unit with actual fate.
Through to the arithmetic expression accumulating operation, a life cycle calculations value and an expection setting value are compared, when the calculated value of certain relay protection product reaches the expection setting value, notify the user that the relay protection product is upgraded, safeguarded or changes.
Also comprise the retired time of relay protection product, reprocess the step that maintenance time is planned in advance.
Form prior notice user with report output.
Type according to the relay protection product is divided into conventional plug-in unit, rapid wear plug-in unit or alternative plug-in unit with it.
Principle of work of the present invention is following:
According to buying device time, the time of making the product, debug time, putting into operation the time, as node, different weights are set with each time point according to operation condition in site, the products-hardware life-span is managed.When certain device calculated value reached expection setting boundary, prior notice user changed or handles.
The beneficial effect that the present invention reached:
Products-hardware is carried out lifecycle management;
Prior notice, planning in advance;
Form product database, classification is safeguarded;
Guarantee the reliable and secure operation of relay protection product.
Description of drawings
The hardware longevity management block diagram of Fig. 1 relay protection product.
Embodiment
Below in conjunction with accompanying drawing the present invention is further described.Following examples only are used for technical scheme of the present invention more clearly is described, and can not limit protection scope of the present invention with this.
As shown in Figure 1, the relay protection products-hardware is carried out equipment control, retired from device buying, production processing beginning until product, every device of every block of plug-in unit, plug-in unit is carried out life cycle management.According to the difference of each time point, the difference of service condition, carry out different weight computings.
Life cycle calculations value arithmetic expression:
Wherein: 0≤A
k≤1;
A
kThe expression weight is used for indicating various process to the products-hardware effect on service life, and it is operating experience that foundation is set, as the system weight parameter of setting up departments is following, can adjust according to actual conditions:
Production, processing link A
k=0.5;
Debugging A
k=0.2;
Stock A
k=0.05;
Transportation A
k=0.1;
Actual motion A
k=1.0;
Safeguard A
k=0.8;
T
kRepresenting operation time, is unit with actual fate.
Through accumulating operation, a calculated value and an expection setting value are compared, system can point out and alarm.
Full station or total system relay protection products-hardware life-span are managed, conventional plug-in unit, rapid wear plug-in unit, alternative plug-in unit are classified, form station level, Complex Structural System management database.The relay protection products-hardware is upgraded and safeguard with report output form prior notice user.
The above only is a preferred implementation of the present invention; Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from know-why of the present invention; Can also make some improvement and distortion, these improvement and distortion also should be regarded as protection scope of the present invention.
