Description
[ technical field ] A method for producing a semiconductor device
The utility model relates to a distribution automation technical field, it is specific, relate to a distribution network automation simulation training system.
[ background of the invention ]
Along with the increasing expansion of the construction scale of a power distribution network, the requirement on power supply reliability is continuously improved, the power distribution network automation industry is rapid, the problems that the power distribution network automation terminal in the power distribution network is various in types, single in function, difficult in fault analysis and the like are brought, and the operation and maintenance pressure on operators is increased rapidly. At present, no special simulation training system for automatic equipment in a distribution network is available in the market, and related personnel can only know related products by means of actual work, so that the personnel cannot master the products sufficiently, and the field operation proficiency is poor. In addition, in the aspect of detection of related products, a relay protection tester is adopted to perform simulation test on a single distribution network automation device at present to check whether equipment is intact.
In recent years, some enterprises put forward simulation training systems, but all the systems adopt fixed hardware equipment, have poor integration level, cannot be flexibly configured, cannot truly simulate various faults of a distribution network, and simultaneously have larger difference of local network architecture operation modes of users, so that the aims of dynamic simulation testing and simulation training are difficult to achieve due to poor pertinence and practicability.
The following are the disadvantages of the prior art:
1) the local real distribution network structure cannot be truly simulated.
The network frame structures of different areas and different power supply companies are different, the operation and maintenance modes are different, the existing simulation system is solidified at the beginning of design, the equipment configuration, the mutual topological structure and the communication mode are difficult to change, the flexibility is poor, and the actual distribution network structure cannot be simulated according to the local real condition of a user. The technology adopts a modular design, can flexibly configure the number of simulation equipment and the contact mode between the simulation equipment, can verify different distribution network automation strategies, and finally determines one or more distribution network automation schemes suitable for a local area through systematic tests.
2) The problems of incomplete and incomplete test, error setting and the like exist in the power distribution automation terminal test.
In most existing distribution network automation schemes, the action logic of the distribution automation terminal is related to the action conditions of the upper and lower terminals, such as an optical fiber differential protection mode, an intelligent distributed protection mode, a voltage current mode, a voltage time mode, and the like. Especially, when the optical fiber differential protection and the intelligent distributed protection are used for field test by a relay protection tester, the field test is not in place and incomplete due to the difficulty in ensuring the synchronization of the applied voltage and the current, and the situations of error setting and error wiring occur. Because the system simulates the whole power distribution grid structure, the current and voltage during the fault are completely consistent with the actual fault. By adopting the system to carry out network access test or debugging before commissioning of the terminal equipment, the problems of the terminal equipment can be found in time, the error of setting the fixed value is avoided, and the defect is prevented from being brought into actual operation.
3) The training effect is poor.
Distribution network automation equipment combines multiple technologies such as relay protection, automation, communication and direct-current backup power, and distribution network switches, operating mechanisms and automation terminals are multiple in variety and manufacturers, so that operation and maintenance personnel are difficult to be familiar with distribution network automation technology. At present, the training from the organization personnel to the field is mainly adopted, and the training effect is poor because only a single set of equipment on the field can not comprehensively know the action condition of the whole looped network switch equipment. The utility model discloses simulated from transformer substation owner become all switches and the automation equipment that the user distributed the electrical room, can simulate multiple switch and operating device, had multiple distribution network automation mode, the security is high, the training environment is good, adopt utility model to join in marriage net automization relevant planning, design, debugging, operation personnel and carry out the technical training, can play the effect of doing the job a lot doubly.
4) The display is not intuitive.
Present relevant system can only look over each equipment running state through backstage or equipment panel, shows directly perceived inadequately, the utility model discloses an inferior gram force simulation lamp area, size and the flow direction that can analog current and voltage show very directly perceived, simple and convenient.
