異等偶發事故所造成電力系統反應之問題，故針對偶發^ 故定義了兩種準則： x 一、 N-1準則：當輸電線路、發電機組或變壓器之任一 設備，於檢修或事故停用情況下，輸電系統仍可正常運轉。 二、 N-2準則：當任二回線（或任兩部最大發電機組)檢 修或事故停用、任一回線及任一部最大發電機組檢修停 用二任一回線及任一部最大發電組事故停用、任一回線^ 修停用及任一部最大發電機組事故停用或任一回線事故】 任一部最大發電機組檢修停用時，輸電系統仍可正常運轉。 一有別於台灣本島電網架構，離島地區在獨立供電系統 及經濟運轉前提下，電力系統為有限的N-1的備轉容量， 因此對於電廠運轉調度及維護較為困難，因此當發生^_2 以上極端事故時很難避免系統全黑，也就是由於突發性事 故引發電力系統崩潰導致大停電事件，不僅造成居民恐 201246740 ’巧，更使經濟蒙受重大損失。有鑑於此，電力公司為

Each remote monitoring station 11, 12 13 14, 15 may have an Ethernet communication interface to communicate with the decision center. As shown in the first figure, 'the decision center 1〇 contains 2 front-end communication processing ° ° 1 〇 1, 1 〇 2 ', which has an Ethernet communication interface, and a communication between the two The switch 1 〇 3 is coupled for communication, and each of the front-end communication processors 101 and 102 is coupled to a communication module 1 〇 1 〇, 1 〇 2 〇 for receiving from the remote monitoring stations.

In addition, in this specific embodiment, each of the front-end communication processors 101, 102 is based on the signals immediately transmitted by the remote monitoring stations 11, 12, 13, 14, 15 Determining whether it is necessary to uninstall the distribution feeders or to trip the transformers. If it is determined that the uninstallation is required, a control command is generated and transmitted to at least one of the remote monitoring stations n, 12, 13, 14, and 201246740 - 'Let the digital wheel sets 140, 150 jump off the circuit breakers of the distribution feeders or transformers, thereby avoiding the situation that the system is completely black in the event of an accident. Furthermore, ^ = system from detection, transmission, calculation to jumping off the evening, stored within ± ea : 200 · :), enabling immediate protection. (_ It is worth noting that in this case, such as βU VII, Lulu-Γ八& II, the best example of the power protection system = = points, the species, respectively, are non-extreme accidents and extremes In the event of an accident, she is not very heavy, the door is QS, the meat is smashed, and the accident is, for example, but not limited to, at a predetermined time, σ@ρ二&, and the jump is stopped; extreme accidents are, for example but not limited to, A continuous peach shutdown. When a non-extreme accident occurs, or any one of them, the power protection system can have two modes of operation, namely, the type of load, and the other is that the decision C is equivalent to jumping hair loss. ^The amount of load is automatically calculated as the unloading generator's power generation and the negative value of the distribution feeder.

In some preferred embodiments, the power protection system further includes an on-line simulation system 16 An offline analysis workstation 160 and a front-end communication processor 161 are connected to the decision center 10 in a regional network for accessing the signals and graphs from the database server 107. (that is, historical and cross-sectional data) for simulation and analysis. In addition to allowing the personnel of the power company to use it as a training tool, the power protection system can be improved from the simulation and analysis process, so as to be able to Avoid system blackouts. Although the foregoing concept of the power protection method of the present invention has been described in the foregoing description of the power protection system of the present invention, for the sake of clarity, a detailed description of the flowchart will be further described below. Referring to the second figure, a flow chart of an embodiment of the power protection method of the present invention is shown. First, as shown in step 210, the detectors are respectively used to detect 201246740 to measure the power generation of the plurality of generators and the load of the distribution feeders; and then, as shown in step 220, the digital input/output modules detect each The state of the circuit breaker of the generator, the distribution feeder, the power line, and the transformer, such as the ΟΝ/OFF state of the circuit breaker; then, as shown in step 230, the remote power monitoring station receives the power generation amount, the load amount, and the circuit breaker The signal of the status is transmitted to the decision center through the communication module; then, as shown in step 240, the decision center uses the signal transmitted by the remote monitoring station to determine whether it is necessary to uninstall the distribution feeders or Jumping off the transformers; when the decision center determines that the uninstallation is required, proceed to step 250, otherwise proceed to step 210; as shown in step 250, the control center generates a control command and transmits the control command to the remote monitoring Finally, as shown in step 260, the remote monitoring stations cause the digital output modules to jump off the distribution feeders or transformers according to the control command. Circuit breaker. Referring to the third diagram, a flow diagram of operational logic in accordance with an embodiment of the present invention is shown. In this embodiment, after the power protection system receives the signals from the remote monitoring stations, it determines whether the order of unloading and unloading needs to be performed according to an operational logic to maintain system output and load stability. For example, when a non-extreme accident occurs (such as no continuous jump stop within 8 seconds) or an extreme accident (such as continuous jump stop within 8 seconds), you can choose to immediately remove the load equivalent to the amount of tripped power generation, or calculate Whether the system's bar-capacity is sufficient to avoid frequent and unnecessary unloading. The present invention is described as a preferred embodiment. First, as shown in step 310, an unloading threshold is automatically calculated according to the power generation of the generators and the load of the distribution feeders to avoid frequent unloading and affect the consumers. Rights. Then, as shown in step 320, when any of the generators is tripped 13 201246740, the center calculates whether the trip power generation amount is greater than the unloading threshold value, and the right trip power generation amount is greater than the unloading threshold value 330, otherwise steps are performed. 34〇. j Shaozhen then, as shown in step 330, the load amount minus the unloading threshold value is immediately removed, which is equivalent to the tripping power generation amount, because the load capacity of the system is sufficient or as shown in step 340, the unloading is performed, and the tripping power generation amount is loaded. . When there is an extreme accident in the gas connection (for example, continuous jumping within 8 seconds), if the first decision is made when the first generator is jumped, the decision center calculates that the load capacity of the generators cannot be unloaded. In the case of two generators, it is necessary to immediately generate the total amount of power generated by the 1^»Xuan 1st generator and the 2nd generator! Load to ensure system security. However, if you skip the second generator when you skip the second generator, you only need to remove the load of the second generator. The same reason can be easily understood by those skilled in the art. It can be extended to multiple trips. The detailed implementation of each of the above steps has been described in detail in the foregoing description of the power protection system and will not be described again. In summary, the power protection system and method of the present invention have at least the following advantages: 1. Overcoming the shortcomings of the prior art that the low-frequency unloading strategy is unloaded, the reaction time is slow, the generator set output state cannot be grasped immediately, and the unloading amount is not & . Second, based on the dynamic balance of output and load, the decision-making center provides an operational logic to enable instant judgment of the state of the accident (such as extreme/non-extreme incidents) and avoid unnecessary unloading, thereby saving the system from blackout. occur.
