The invention discloses an RTDS simulation system of a static variable frequency system. The RTDS simulation system comprises a real-time digital simulator RTDS, signal interface equipment and static variable frequency control protection equipment, wherein the real-time digital simulator RTDS is connected with the signal interface equipment through an optical fiber, and the signal interface equipment is connected with the cable of the static variable frequency control protection equipment. The RTDS simulation system of the static variable frequency system can check the static variable frequency system capacity, main loop topology, unit start-up time and the like, test the function of static variable frequency system control and protection equipment and test control parameters; when the system topology is changed or the primary system parameters are changed, the experiment can be performed after correcting a simulation model.

The present invention relates to a method, a computer program product and a system of adding new static data variables and initialisation routines for these variables as part of a method of replacing a current version of a computer program with a replacement version of the program concurrently with the execution of the program on a computer system. This replacement version consists of new machine code completely replacing the existing version, new static data variables and initialisation routines for these variables. The content of the existing static variables will be preserved during the application of the concurrent patch. The concurrent patch can be revoked and the new static data variables can be removed such that the computer program that was executed before the application of the concurrent patch will be executed again.

A system and associated method for directing to recompile a class with a static variable of the class in a Java platform are disclosed. The class is defined with at least two implementations that are selectively compiled and executed a value of the static variable. The value of the static variable of the class is modified to a new value depending on characteristics of a runtime environment in which the method is executed. The class is recompiled and the new value is set for the static variable of the class. A debugger performs a hot code replacement of the class with the recompiled class.

The invention relates to a cold start method of a gas-and-steam combined cycle power generating unit. The cold start method specifically comprises the following steps that 1, under dragging of a static variable-frequency starting device, the rotating speed of a gas turbine is stabilized at m rpm; 2, steam is fed from adjacent machines, specifically, a turbine conducts impulse starting on a warmingturbine through an intermediate-pressure cylinder, at this time, a high-pressure cylinder forwards or reversely feeds steam, the rotating speed of the turbine is stabilized at m rpm, an SSS clutch begins to be engaged in place, the steam fed from the adjacent machines conducts impulse starting on the turbine, and the gas turbine is driven by the SSS clutch; 3, the output of the static variable-frequency starting device of the gas turbine is reduced to be 0, the quantity of the steam fed from the adjacent machines is increased, and the rotating speed of the medium-speed warming turbine is maintained for turbine warming; 4, when the calculation temperature of an intermediate-pressure shaft in the turbine is larger than 200 DEG C, the medium-speed warming turbine stage is finished, or the turbine warming time of the medium-speed warming turbine stage is determined according to the actual on-site working conditions; and 5, after the medium-speed warming turbine stage is finished, the output of the static variable-frequency starting device of the gas turbine is gradually increased, the quantity of the steam, fed from the adjacent machines, of the turbine is gradually decreased to be 0,the turning states of the gas turbine and the turbine are restored, or the turbine is controlled to be smaller than the gas turbine in ignition rotating speed, the gas turbine slows down to directlyignite, and then the combined cycle power generating unit is started in a warm or hot start mode.

The invention provides a method for detecting the CPU (Central Processing Unit) occupancy rate of vxWorks. The method comprises the steps: (S1) starting a task with the lowest priority before starting a user task, and progressively increasing a static variable and recording count values at the start of a statistical time until the statistical time ends; (S2) saving the recorded static variable count value to a comparison base number corresponding to the end of the statistical time, and resetting the static variable; (S3) progressively increasing the static variable and recording the count values in a statistical time during the task with the lowest priority when the vxWorks is idle; (4) starting a task with relatively high priority, and calculating the increment value of the static variable in each statistical time; (S5) calculating the CPU occupancy rate by using the ratio of the recorded static variable increment value to the comparison base number. The invention further provides a corresponding system for detecting the CPU occupancy rate of the vxWorks. The method and the system, provided by the invention, have the advantages that a high-precision clock is not required, and the cost is reduced; the implementation is simple and easy, the flexibility is high, and the universality is strong.
