Consider a 2.5 MW, 4000 V, 40 Hz salient pole PMSG wind energy conversion system (WECS). The parameters of the generator are given in Table 1. The generator operates with an MPPT scheme. At a wind speed of 6 m/s, the generator operates at 0.5pu rotor speed. At given wind and generator speeds, the MTPA can be achieved at the q-axis current of 214.82 A (peak).

cs = s.accept();. You selected 2. 1.21/8.5 pts Matching. Match each socket function call to the sequence it will appear on a Java TCP client. The first/earliest call is assigned the number 1. The earlier is a function call, the smaller is its assigned number. The statements must be compatible (i.e., use appropriate variables from earlier valid statements). - If a call is NOT absolutely necessary, assign it the number 99. - If a call is NOT applicable to a TCP server client, assign it the number 77. - If two calls can be interchanged, assign them the same number. b = s.getOutputStream(); s = new ServerSocket(..); a = cs.getInputStream(); s.close() 77 1 3 99 cs = s.accept(); 2 b.write(...) 4 s = new Socket(..); 99

7. A signal $x_a(t)$ contains two frequencies 10kHz and 15kHz. We want to suppress the 15kHz component to 50 dB attenuation, while passing the 10kHz component with less than 0.25 dB attenuation. Design a minimum order elliptic filter analog filter to perform this filtering operation. By plotting the log-magnitude response, verify the design.

Converting Kelvin to Celsius is easy. Simply subtract 273.15 from Kelvin and you get Celsius. Here is a sample formula: C = K - 273.15 The instructions below need to be organized in the correct order (sequence) to convert Kelvin to Celsius for a range of temperatures starting at -0°K in increments of 11 °K, and stopping at 99 °K. Organize the logic to loop through the range of temperatures and print out only the last °C value (the value associated with 99 °K). [Your environment file must contain evidence of this task to receive full credit.] console(m7) #Print message to console kv = (-0) while (kv < 99): #Comment, prior line calculates Celsius value m7 = 'C is ' + str(cel) + ' K is ' + str(kv) cel = kv - 273.15 #Comment, prior line builds a message kv = kv + 11
