PSCAD排序
MMC里如何对于多个子模块电容电压排序，还需要知道排序后的子模块电容的编号，从而确定是否让该子模块投切。有相关算法吗，求求大佬帮忙!代码仅为讲解原理所用，未经过验证

module sortMod
type UDT
real x, y
character str*40
end type
!升序排列
contains
!单元素排序
subroutine sortScale(a)
implicit none
real a(:), b
integer i, j
do i = 1, size(a)-1
do j = i+1, size(a)
if(a(i)>a(j)) then
b=a(i)
a(i)=a(j)
a(j)=b
end if
end do
end do
end subroutine
!按第一列对整行排序
subroutine sortArray(a)
implicit none
real a(:,:), b(size(a,1))
integer i, j
do i = 1, size(a,2)-1
do j = i+1, size(a,2)
if(a(1,i)>a(1,j)) then
b=a(:,i)
a(:,i)=a(:,j)
a(:,j)=b
end if
end do
end do
end subroutine
!按前两列对整行排序
subroutine sortArray2(a)
implicit none
real a(:,:), b(size(a,1))
integer i, j
do i = 1, size(a,2)-1
do j = i+1, size(a,2)
if(a(1,i)==a(1,j)) then
if(a(2,i)>a(2,j)) then
b=a(:,i)
a(:,i)=a(:,j)
a(:,j)=b
end if
else if(a(1,i)>a(1,j)) then
b=a(:,i)
a(:,i)=a(:,j)
a(:,j)=b
end if
end do
end do
end subroutine
!按前两列对整行排序，效果同sortArray2, 但更简洁
!适用于按照前n列排序
subroutine sortArray3(a)
implicit none
real a(:,:), b(size(a,1)), hugeval
integer i, j
hugeval = maxval(abs(a(2,:)))*1.1 !大于第二列最大绝对值
do i = 1, size(a,2)-1
do j = i+1, size(a,2)
if(a(1,i)*hugeval+a(2,i)>hugeval*a(1,j)+a(2,j)) then
b=a(:,i)
a(:,i)=a(:,j)
a(:,j)=b
end if
end do
end do
end subroutine
!自定义数据排序
subroutine sortUDT(a)
implicit none
type(UDT) a(:), b
integer i, j
do i = 1, size(a)-1
do j = i+1, size(a)
if(a(i)%x>a(j)%x) then
b=a(i)
a(i)=a(j)
a(j)=b
end if
end do
end do
end subroutine
end module
