Embodiment Construction

[0033] The present invention will be further described below in conjunction with the accompanying drawings.

[0034] The purpose of large interlocking: the boiler, steam turbine, and generator of the unit have their own protection systems, and the action of any part of the protection system will affect the safe operation of other parts. At present, the unit has gradually developed into a relatively complete logic system. Judgment and control functions are processed by a special device, which is the large interlock protection system of the unit unit.

[0035] The large interlock protection test needs to be carried out before each ignition of the unit. The purpose is to verify the correctness of the logic and wiring of the interlock protection circuit between the three main engines, and to ensure the safety of the unit and equipment.

[0036] as attached figure 1 And attached figure 2 , based on Ovation's GB assembly language to realize the method of large interlocking test f...

Abstract

The present invention discloses a method for implementing large interlocking test function group configuration based on a GB assembly language of Ovation. A picture configuration function of the GB assembly language of Ovation is used for constructing a temporary enforcement signal list and a large interlocking test project steps selection map, all enforcement points in a large interlocking function group are implemented by using a programming function of the GB assembly language of Ovation, and specifically, statuses and values of the points are changed by executing the #180 program of GB. According to the method for implementing large interlocking test function group configuration based on a GB assembly language of Ovation provided in the present invention, continuous enforcement and enforcement removal of enforcement points in the large interlocking function group are implemented without modifying any underlying logic. In addition, correctness of each time of execution of the function group can be ensured only by using a simulation system and verifying in field correctness of the enforcement points.

Description

technical field [0001] The invention belongs to the technical field of generators, and in particular relates to a method for realizing large interlocking test function group configuration based on Ovation's GB assembly language. Background technique [0002] The large interlocking test of the generator is scheduled to be carried out before the boiler MFT is reset and ignited. At this time, the main steam flow does not meet the conditions of greater than 650t / h, so any machine trip is required (the main steam flow is less than 650t / h, and the machine trip does not trip) All the test steps need to force the main steam flow rate to be greater than 650t / h to 1, and the condition needs to be released before the MFT is reset. This process needs to be checked back and forth by the thermal control personnel, which is very time-consuming and cumbersome. [0003] Through the traditional method of mandatory points, due to the different test personnel or different working conditions eac...
