对grwave PC版需要一台IBM PC / AT或等效
地波场强计算,高频地波场强衰减计算，高频电磁波地波传播计算仿真，Fortran源程序，可以在cirr公开网址上获得。- The PC version of GRWAVE requires an IBM PC/AT or equivalent
(80286 microprocessor) with a math co-processor and a minimum of
256 kilobytes of memory.
Disk Contents:
GRWAVE is supplied on a 3.5" or 5.25" disk which
contains three main files. These are GRWAVE.EXE, GRWAVE.FOR
and GRWUSR.MAN. GRWAVE.EXE is executable machine language code.
GRWAVE.FOR is the FORTRAN source code. Compilation of this
source code to produce an executable code requires a FORTRAN
compiler which supports double precision complex arithmetic.
Microsoft FORTRAN Version 4.01 was used to compile and link
GRWAVE.FOR to produce GRWAVE.EXE. Compilation has also been
tested with Lahey FORTRAN F77L [*]. It is known the IBM
Professional FORTRAN will not work because of a lack of support
for double precision complex arithmetic.
[*] Note: GRWAVE uses a function, DREAL, which is not an

12?ADC ??Multisim
STC8F2K64S2系列单片机提供16个中断请求源，分别是：外部中断0中断（int0）、定时器0中断（timer0）、外部中断1中断（int1）、定时器1中断（timer1）、串行端口1中断（uart1）、低压检测中断（lvd）。，串行端口2中断（UART2），串行外围接口中断（SPI），外部中断2中断（INT2），外部中断3中断（INT3），定时器2中断（Timer2），外部中断4中断（INT4），定时器3中断（Timer3），定时器4中断（Timer4），比较器内部PT（CMP），I2C总线中断。除了外部中断2、外部中断3、定时器2中断、定时器3中断、定时器4中断和比较器中断固定是最低优先级中断外，所有其他中断都有四个可设置的中断优先级。(STC8F2K64S2 series single chip microcomputer provides 16 interrupt request sources, which are: external interrupt 0 interrupt (INT0), timer 0 interrupt (Timer0), external interrupt 1 interrupt (INT1), timer 1 interrupt (Timer1), serial port 1 interrupt (UART1), low voltage detection interrupt (LVD), serial port 2 interrupt (UART2), serial peripheral interface interrupt (SPI), external interrupt 2 interrupt (INT2), external interrupt 3 interrupt (INT3), Timer 2 interrupt (Timer2), external interrupt 4 interrupt (INT4), timer 3 interrupt (Timer3), timer 4 interrupt (Timer4), comparator interrupt (CMP), I2C bus interrupt. Except that the external interrupt 2, the external interrupt 3, the timer 2 interrupt, the timer 3 interrupt, the timer 4 interrupt and the comparator interrupt fixed are the lowest priority interrupts, all the other interrupts have four interrupt priorities that can be set.)

说明： 讨论了直接电流控制的几种控制结构，并建立了相应的仿真模型， 进行了仿真和比较分析。研究了它们在稳态性能和动态性能上的优缺点。其 中重点讨论了采用空间电压矢量调制方法(SVPWM)跟踪给定电压矢量，来控 制STATCOM的电流产生，并且采用直流侧电压可交给定。(Several control structures of direct current control are discussed, and corresponding simulation models are established, and simulation and comparative analysis are carried out. Their advantages and disadvantages in steady state performance and dynamic performance were studied. It focuses on the use of space voltage vector modulation (SVPWM) to track a given voltage vector to control the current generation of the STATCOM, and the DC side voltage can be applied.)
